SUMMARY:Physical Chemistry Seminar 228: Hannah Shafaat
DESCRIPTION:Shafaat Flyer \nTitle: Model Metalloenzymes to Catalyze the Reactions of Early Life \nAbstract: Metalloenzymes catalyze the challenging chemical reactions that lie at the core of vital life processes\, from carbon and nitrogen fixation to photosynthesis and respiration. Native metalloenzymes use only earth-abundant transition metals and operate under mild conditions\, accessing reactivity that remains largely out of reach for synthetic systems. Given the importance of these fundamental processes in the context of energy\, environment\, sustainability\, and human health\, gaining molecular-level understanding into how metalloenzymes work is of the utmost importance. To this end\, we are developing protein-based models as structural\, functional\, and mechanistic mimics of naturally occurring metalloenzymes. Targets to be discussed in this presentation include hydrogenase\, carbon monoxide dehydrogenase (CODH)\, and acetyl coenzyme A synthase (ACS). These nickel-containing enzymes are implicated in chemoautotrophic origins of life and play key roles in the metabolisms of ancient bacteria and archaea. However\, while these enzymes are highly functional within their cellular environment\, most are costly to isolate\, sensitive to external conditions\, and generally poorly suited for large-scale application. Additionally\, the multimetallic active sites and auxiliary cofactors obscure distinguishing spectroscopic features and render detailed analyses challenging. As a result\, the molecular mechanisms of catalysis remain relatively poorly understood\, thwarting efforts to build biomimetic synthetic systems that act with the efficacy of native enzymes. By combining functional studies of our model proteins with diverse spectroscopic techniques and computational investigations\, we can obtain a comprehensive understanding of how the electronic and geometric structures dictate reactivity in each system. Reconstructing functional metalloenzymes “from the ground up” offers direct insight into the fundamental chemical principles driving the natural systems. Looking forward\, we hope to apply these principles towards engineering effective systems for energy conversion reactions while learning about fundamental chemical transformations that may underlie the evolution of prebiotic processes into early life.

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Prashant Jain
DESCRIPTION:Flyer: Prof. Prashant Jain Flyer \nTitle: “The Chemical Potential of Light” \nAbstract: The interaction of light with molecules can be used to access new modes of chemical reactivity; however\, this interaction is often difficult to exploit in a universal manner. I will describe how plasmonics is proving to be a general strategy for interfacing photons with molecules and activating chemical transformations and even inducing emergent chemistry. In my laboratory\, catalysts based on plasmonic nanoparticles are allowing light to be used as a redox equivalent in chemical reactions\, for promoting non-equilibrium chemical processes\, for modifying product selectivity\, for photosynthesizing fuels\, and for boosting electrochemical conversions. I will provide a deeper view of the excited-state structures\, species\, and mechanisms that underlie these phenomena at the nanoparticle–solution interface.

SUMMARY:Houk-Jung Organic Colloquium 247: Prof. Joel Smith
DESCRIPTION:Smith Flyer \nTitle: Dearomative Alkaloid Synthesis \nAbstract: Biologically active alkaloids continue to serve as a means of biomedical discovery in addition to serving as forcing functions for the invention of new chemical transformations. Structurally\, many of these natural products and rationally designed drugs also contain one or more piperidine rings\, making it the most common nitrogenous heterocycle amongst approved small-molecule therapeutics. Thus\, the concise redox-economic construction of these heterocycles in the context of target-oriented synthesis has become a recent research focus in our lab. In particular\, leveraging controlled and selective dearomatization reactions has enabled the concise synthesis of several natural products and approved pharmaceuticals from simple feedstock pyridines. Our lab’s recent synthetic efforts related to alkaloids from the lupin\, ergoline\, aspidosperma\, morphinan and manzamine families of alkaloids will be discussed\, articulating the breadth of targets that can be accessed by this strategic approach. In addition\, both fundamental and translational opportunities afforded by our work in this area will be highlighted.

SUMMARY:Physical Chemistry Seminar 228: Franz Geiger
DESCRIPTION:Geiger Flyer \nTitle: Photonic Electrochemistry \nAbstract: Water’s oxygen is the electron source in the industrially important oxygen evolution reaction\, but how water interacts with an electrode remains enigmatic. While much microscopic insight into the Stern layer comes from atomistic simulations or joint theory-experiment approaches\, water’s strong absorber problem has clouded our view of how water aligns in response to applied potentials. Here\, we employ nonlinear optics with a non-resonant pulse triplet at Ni:NiOx electrodes during cyclic voltammetry at pH 13 to quantify 𝒩water↓\, the Stern layer water molecules pointing their oxygen atoms towards the electrode\, and Ftot\, the total interfacial potential. 𝒩water↓ varies sigmoidally with applied potential\, U\, but linearly with Ftot. While there is no net alignment at U=0.4 V\, 3/4 of a water monolayer align at U=0.6 V and Eflip\, the energy associated with water flipping\, matches liquid water’s cohesive energy. At U=0.8 V\, all Stern layer water molecules (1 x 10^15 cm^-2) align and Eflip matches the cohesive energy of ice. The current density is exponentially sensitive to 𝒩water↓ and Eflip. Our experiments provide new benchmarks for electrical double layer models and a diagnostic tool for molecular electrochemistry.

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Elizabeth Young
DESCRIPTION:Flyer: Prof. Elizabeth Young Flyer \nTitle: From Photodynamic Therapy to Photovoltaics: Photophysics of Pd(II)biladiene and Charge Carrier Dynamics in Thin Films of Light Harvesting Sb2S3 \nAbstract: Solar light harvesting and interconversion of solar energy into either electricity or driving force for small molecule activation reactions are critical to the production of energy and other processes that our society requires to function. In this talk\, I will discuss two project united by photochemistry\, each with their own application. In the first vignette\, I will discuss a porphyrinoid complex\, called a Pd(II)biladiene\, This Pd(II)biladiene moiety was designed for use as a photosensitizer drug for photodynamic therapy. Up until this point\, the excited-state dynamics of such biladiene complexes have been virtually unexplored. During our work on this moiety\, we discovered that while excitation into the lowest-energy absorption feature of the Pd(II)biladiene complexes produces expected photophysics\, interestingly\, excitation into higher-lying excited states resulted in an additional\, unexpected lifetime. I will discuss our work to propose the cause of this unexpected behavior. In the second vignette\, I will discuss our recent work on stibnite (Sb2S3)\, which can be employed as the photoactive layer in next generation thin-film solar cells. Sb2S3 is of particular interest due to the suitable band gap of 1.7 eV and high absorption coefficient (1.8 × 105 cm–1 at 450 nm). I will present our work using transient absorption spectroscopy to directly observe carrier diffusion\, electron transfer\, hole transfer and charge recombination through uniform ultra-thin (< 3 nm) layers of insulating or transport materials deposited by atomic layer deposition (ALD) that are coupled to photo-active materials. Our results will be used to correlate the structure and function of material thickness and transport type to develop a fundamental\, detailed\, quantitative understanding of photo-induced ET dynamics through thin films of materials.

SUMMARY:Houk-Jung Organic Colloquium 247: Prof. Abby Knight
DESCRIPTION:Knight Flyer \nTitle: Biomimetic Hierarchical Structure in Synthetic Macromolecules \nAbstract: The remarkable functions of proteins\, from refined binding profiles to efficient catalysis\, are currently unrivaled by synthetic macromolecules due to complex hierarchical structure in natural systems. Inspired by this grand challenge\, the Knight group is at the interface of chemical biology and polymer science\, developing synthetic strategies to control hierarchical structure and high-throughput platforms to understand fundamental design principles underlying macromolecule conformation. These research efforts are motivated by the need for innovative strategies to address global health and environmental challenges\, where our foundational work informs the de novo design and development of functional polymeric materials.

SUMMARY:Physical Chemistry Seminar 228: Lisa Fredin
DESCRIPTION:Fredin Flyer \nTitle: Modeling Photoactive Organic Materials \nAbstract: Chemical intuition is well developed for single molecules but the extent to which disorder in solid state molecular materials contributes to their properties is poorly understood. In particular\, molecular materials move charges in some directions much more efficiently than others due to the packing of the molecules. Noncovalent interactions between the molecular components mean that dynamic disorder in these materials can have a large impact on the electronic properties of these materials at room temperature. This work explores how packing and vibrations in organic crystals affect charge transport in light driven devices. In particular\, the size of dynamic disorder due to phonons or electronic excitation of molecules in the crystal is predicted for well-ordered high-mobility single crystals.

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Phillip J. Milner
DESCRIPTION:Flyer:Prof. Phillip Milner Flyer \nTitle: “Simplifying Synthesis at the Interface of Organic and Materials Chemistry” \nAbstract: Porous framework materials\, including metal-organic frameworks (MOFs)\, are highly tunable materials with myriad potential applications ranging from chemical separations to gas storage to catalysis. This is due to the unusual local environment offered by their pores. Herein we will discuss how this tunability can be used to unlock new reactive species relevant to organic synthesis and catalysis\, focusing on fluorination chemistry\, which is critical to the pharmaceutical\, polymer\, and agrochemical industries. We will also draw inspiration from organic chemistry for the design of new chemical separations and electrocatalytically active materials.

SUMMARY:Distinguished Lecture Series: Prof. David Christianson
DESCRIPTION:Title: Directing Biosynthesis with Modular Architecture in Terpene Cyclases \nAbstract: Terpene cyclases catalyze the most complex chemical reactions in biology\, in that more than half of the carbon atoms in an isoprenoid substrate undergo changes in bonding or hybridization during a multi-step cyclization cascade that proceeds through multiple carbocation intermediates. Although the substrate pool for these enzymes is limited to only a handful of linear isoprenoids\, more than 100\,000 terpenoid natural products have been identified to date. Crystal structures of terpene cyclases reveal common\, modular protein folds that direct unique catalytic strategies underlying this exquisite chemodiversity. Most recently\, structural studies of bifunctional assembly-line terpene synthases using cryo-EM and other biophysical techniques show how the first two steps of terpene biosynthesis are combined in nanoscale oligomeric assemblies. Cluster channeling within the oligomer ensures efficient carbon management in wild-type and mutant enzymes.

DESCRIPTION:Baker Flyer \nTitle: Observing Ultrafast Electron Motion in Catalytic Systems: New Ways to Visualize Charge and Spin Dynamics at Interfaces \nAbstract: Understanding and controlling electron dynamics at interfaces is at the heart of numerous applications ranging from heterogenous catalysis to information processing. To directly observe these dynamics\, we have developed ultrafast XUV reflection spectroscopy as a surface sensitive analog of time-resolved x-ray absorption. In these measurements\, high harmonic generation of attosecond to femtosecond XUV pulses enables real-time observation of charge and spin dynamics with element specificity\, ultrafast time resolution\, and near atomic layer surface sensitivity. This talk will highlight recent studies of surface electron dynamics in materials ranging from photocatalysts to magnetic semiconductors to systems displaying chiral-induced spin selectivity (CISS). In addition to ultrafast electron transfer\, we also study the interfacial solvation structure in electrocatalytic systems using in-situ sum frequency generation vibrational spectroscopy. This complimentary tool enables direct measurement of solvent-mediated electric fields at catalytic interfaces\, which are found to significantly influence the kinetics of electrochemical CO2 activation and reduction. Last\, I will briefly describe the National eXtreme Ultrafast Science (NeXUS) facility. This $10M infrastructure project provides attosecond and femtosecond pulses of XUV light with tailored bandwidth to a suite of experimental end-stations enabling molecular and material characterization with unprecedented temporal and spatial resolution. This facility\, which is supported by the National Science Foundation\, will soon become an international open-access user facility serving the entire chemical\, physics\, and materials communities.

SUMMARY:Inorganic Student Exit Talk: Austin Ready
DESCRIPTION:Flyer: Austin Ready Flyer \nTitle: Boron Clusters as Robust Building Blocks for the Expansion of Carbon-Based Chemistry \nAbstract: Due to a delocalization of electron density\, polyhedral boron clusters are often described as three-dimensional analogues of planar aromatic molecules such as benzene. Despite this electronic similarity\, boron clusters can have drastically different chemical and physical properties compared to their carbon-based counterparts. In particular\, our group studies the twelve vertex-containing boron cluster dodecaborate— [B12H12]2-— as a synthetic building block whose chemical reactivity and electrochemical behavior can be rationally modified by substituting the B-H vertices on the periphery of the cluster with various reactive functional groups. I will discuss the synthesis\, chemical properties\, and structure/bonding considerations pertaining to these derivatized B12 clusters\, as well as potential applications relevant to the fields of materials science and energy storage.

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Shabnam Hematian
DESCRIPTION:Flyer: Prof. Shabnam Hematian Flyer \nTitle:Unconventional Approaches for Mediating Redox Reactions \nAbstract: Reactions involving electron transfers are known as oxidation-reduction\, or redox\, processes\, common and vital to our daily lives. Redox reactions lie at the heart of chemical\, biological\, environmental\, and energy sciences and technologies. Here\, we show how employing unconventional approaches and blueprints to a broad range of redox reactions taking place within homogeneous photocatalysts\, protein scaffolds\, and electrochemical systems provides an avenue for novel chemistries. Together\, our studies showcase examples of redox processes proceeding under mild conditions\, with some being driven by light or an external bias. Specifically\, we investigate the photoactivation of metal-oxo bonds in coordination compounds\, mechanism and function of a new class of copper enzymes\, and novel electrolyte materials for use in organic redox flow batteries. Importantly\, the diversity of molecular structures\, functions\, and mechanisms involved in these examples will highlight the versatility and modularity of the redox reactions and their vital role in realizing a sustainable future.

SUMMARY:The 2023 M. Frederick Hawthorne Symposium
DESCRIPTION:Flyer: Hawthorne Symposium 2023 flyer \nSchedule Brochure:Hawthorne Symposium Brochure \nProfessor M. Frederick Hawthorne (August 24\, 1928 – July 8\, 2021) was a true chemistry pioneer\, discovering boron cluster structures that have paved the way in inorganic\, organometallic\, material\, nanotechnology\, and medicinal sciences. His award-winning work in boron chemistry and time as a distinguished Professor of Chemistry at UCLA have not only shaped and broadened the field\, but also touched the lives of countless students\, faculty\, researchers\, friends\, and family. In honor of his contributions\, the American Chemical Society established the “M. Frederick Hawthorne Award in Main Group Inorganic Chemistry” in 2020. The M. Frederick Hawthorne Symposium aims to celebrate and honor these recipients\, who have made significant contributions to chemistry involving the elements of groups 1\, 2\, and 13-18\, with special consideration given to demonstrated creativity and independence of thought\, in keeping with the example provided by the late Professor Hawthorne. The 2022 M. Frederick Hawthorne Symposium is made possible by the Raymond and Dorothy Wilson Endowment.
