SUMMARY:Physical Chemistry Seminar 228: Bryan Changala
DESCRIPTION:Title: “Illuminating Exotic Chemistry and Physics with Single-Quantum-State Spectroscopy” \nAbstract: Molecules are amongst the most complex objects that can be controlled and studied at the individual quantum state level. In this talk\, I will introduce some of the extraordinary advances made in the last decade by the application of AMO physics tools\, including cavity-enhanced optical frequency comb and microwave techniques\, to such quantum-state-resolved spectroscopy. These precision light-matter probes have redrawn the limits of molecular complexity that can be characterized and controlled in the laboratory\, enabling scientists to address important chemical and physical problems from a fundamental\, bottom-up perspective. I will showcase these applications in achieving rovibrational quantum-state spectroscopy of the C60 fullerene (the largest molecule for which this has been achieved); revealing the unexpectedly rich chemistry that occurs in extreme astrophysical environments; and exploring the unique electronic properties of metal-ligand complexes critical to applications in quantum science and metrology. \nDr. Bryan Changala Flyer

SUMMARY:Physical Chemistry Seminar 228: Giulia Palermo
DESCRIPTION:Prof. Giulia Palermo Flyer \nTitle: Dynamics and mechanisms of CRISPR-Cas9 through the lens of computational methods \nAbstract: The clustered regularly interspaced short palindromic repeat (CRISPR) genome-editing revolution established the beginning of a new era in life sciences. I will report the role of state-of-the-art computations in the CRISPR-Cas9 revolution\, from the early refinement of cryo-EM data to enhanced simulations of large-scale conformational transitions. Molecular simulations reported a mechanism for RNA binding and the formation of a catalytically competent Cas9 enzyme\, in agreement with subsequent structural studies. Inspired by single-molecule experiments\, molecular dynamics offered a rationale for the onset of off-target effects\, while graph theory unveiled the allosteric regulation. Finally\, the use of a mixed quantum-classical approach established the catalytic mechanism of DNA cleavage. Overall\, molecular simulations are instrumental in understanding the dynamics and mechanism of CRISPR-Cas9 and pave the way for a new field of computational studies aimed at deciphering and engineering genome editing systems.

SUMMARY:Physical Chemistry Seminar 228: Colin Nuckolls
DESCRIPTION:Prof. Colin Nuckolls Flyer \nTalk Title: Putting Molecules into Materials \nAbstract: This presentation will detail our efforts to create materials from contorted aromatic molecules. In particular\, I will discuss how to create ladder polymers from helicenes and twistacenes building blocks. These materials have extraordinary properties as materials. The helicenes have the largest chiroptic response of any molecular species. The twistacenes excel as photovoltaics\, photodetectors\, batteries\, and pseudocapacitors. The presentation will discuss these opportunities.

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.

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: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: 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:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Professor Jinyong Liu
DESCRIPTION:Flyer: Prof. Jinyong Liu Flyer \nTitle: “Photodegradation of PFAS: Mechanistic Insights and Technology Development” \nAbstract: The list of PFAS pollutants is expanding rapidly. PFAS pollutants have various chain lengths and end functional groups. These structural features substantially impact the molecular reactivity under reductive and oxidative treatment. The efficacy and efficiency of PFAS degradation systems also depend on solution chemistry\, such as pH and the source of reducing/oxidizing species. This presentation will summarize our recent findings from treating over 60 legacy and emerging PFAS structures. The structure-reactivity relationship and system performance improvement will benefit the design of remediation systems for most PFAS pollutants.

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Professor Yong Yan
DESCRIPTION:Flyer: Prof. Yong Yan Flyer \nTitle: “Perovskite Semiconductors For Photocatalytic Organic Synthesis” \nAbstract: Heterogeneous catalysis is responsible for the vast majority of chemical transformations\, yet the direct employment of chiral solid catalysts for asymmetric synthesis is mostly overlooked. Our lab proved that photophysical properties of lead halide perovskites already proved for photovoltaics\, also should be of interest in photoredox organic synthesis. Because the key aspects of these two applications are both relying on charge separation and transfer. We demonstrated that perovskites nanocrystals are exceptional candidates as photocatalysts\, not only for fundamental organic reactions but also active for elusive asymmetric organic synthesis. Chiral 1-phenylethylamine (PEA)-hybridized perovskite PEA/CsPbBr3 NC photocatalysts exhibit an enantioselective (up to 99% enantiomer excess) avenue to produce N–C axially chiral N-heterocycles\, i.e.\, N-arylindoles from N-arylamine photo-oxidation. Mechanistic investigation indicated a discriminated prochiral binding of the N-arylamine substrates onto the chiral-NC surface with ca. −2.4 kcal/mol enantiodifferentiation. Our perovskite NC heterogeneous catalytic system not only demonstrates a promising strategy to address the long-term challenges in atroposelective pharmaceutical scaffold synthesis but also paves the road to directly employ chiral solids for asymmetric synthesis.

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Timothy Johnstone
DESCRIPTION:Prof. Timothy Johnstone Flyer \nTitle:“Synthesis\, Isolation\, and Exploration of the Chemistry of Kinetically-Stabilized Pnictine Oxides” \nAbstract: The light pnictine oxides R 3 NO\, R 3 PO\, and R 3 AsO comprise a well-characterized class of monomeric molecules with a tetrahedral geometry about the pnictogen center. In contrast\, the preparation of the corresponding Sb and Bi species has long proved challenging. For the heavier pnictogens\, reduced orbital overlap with oxygen increases charge separation\, which in turn increases the electrophilicity of the pnictogen and the nucleophilicity of the oxygen. Furthermore\, the heavier pnictogens have an increased propensity to expand their coordination spheres. Consequently\, stibine oxides and bismuthine oxides occur as oligomeric/polymeric materials. We have recently employed a kinetic stabilization strategy to isolate the first example of an unperturbed monomeric stibine oxide. We have examined the electronic structure of the newly isolated stiboryl functional group using a variety of physical and theoretical techniques. These investigations have guided our exploration of the reactivity of this previously inaccessible unsaturated (heavy pnictogen)–oxygen bond

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Brandon Jolly and Yi Chen
DESCRIPTION:Flyer: Brandon Jolly and Yi Chen Flyer \nSpeaker: Brandon Jolly \nTitle: Spatial Control in Multi-step\, Multi-catalyst Organometallic Processes \nAbstract: Spatial localization is one method in which biology manages its complex network of multi-step and/or multi-catalyst processes. For example\, encapsulation of enzymes via compartmentalization allows for the efficient generation and utilization of intermediate species along a biochemical pathway. Much work has been devoted to applying compartmentalization for efficient in vitro enzyme cascades both theoretically and experimentally. However\, only recently has attention been given to spatial localization in the context of organometallic catalysis experimentally\, with no theoretical insights. Therefore\, we developed a kinetic model to evaluate and understand the effect compartmentalization may have on a multi-step organometallic process\, such as a typical catalytic cycle. A key design principle born out of this work is that compartmentalization is predicted to benefit organometalic catalysis if diffusion into/out of the compartment is kinetically comparable to\, or slower than the catalytic cycle itself\, which is tunable via compartment morphology. Next\, we then set out to extend the concept of spatial localization in organometallics to multi-catalyst processes. Specifically\, electrocatalytic CO2 reduction integrated to Pd catalyzed polyketone synthesis was chosen as a target multi-catalyst system that may benefit from spatial control. Ultimately\, we demonstrate the generation and consumption of CO from CO2 reduction to co-polymerization with ethylene in one pot\, with external control over %CO incorporation into the polymer via applied current\, which is unattainable without spatial control. \nSpeaker: Yi Chen \nTitle: Generate Gradient in Electrochemical Microfluidic Systems to Investigate P. Aeruginosa Metabolic Regulation Kinetics on Single Cell Level \nAbstract: Comprehending how bacterial metabolism adapts to environmental changes\, like oxygen abundance variation\, is important in microbial ecology and has potential applications in disease treatment and bacterial infection. Previous research primarily centered on the collective regulatory responses in bulk culture study while single-cell level understanding of bacterial regulation kinetics still remains a challenge. To address the challenge\, we developed an electrochemical microfluidic system to generate microscopic oxygen and hydrogen peroxide concentration gradients\, simulating the intricate micrometer-scale environments inhabited by bacteria. Particularly\, we cultivated P. aeruginosa in the generated oxygen gradient and investigated its metabolic regulation kinetics on single-cell level\, specifically with regard to the concentration of adenosine triphosphate (ATP)\, in response to environmental oxygen spatial variation and temporal oscillation.

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Sundargopal Ghosh
DESCRIPTION:Title: “Coordination Chemistry of Diborane(4) and Diborane(6)” \nAbstract: The fascinating aspect of metallaborane chemistry is that several classic organometallic complexes that defined fundamental structural and bonding paradigms are mimicked by many isoelectronic metallaborane analogues.[1] In this connection\, diborane compounds not only mimics several classic organometallic compounds but also they have been extensively explored for the broad understanding of the chemical bonding and catalysis.[2] For example\, we have recently synthesized and structurally characterized a bimetallic diborane(4) which mimics Cotton’s dimolybdenum–alkyne complex [{CpMo(CO)2}2C2H2].[3] Also\, we have isolated the first classical diborane(5) [B2H5]-\, in which the sp2-B center is stabilized by the electron donation from tantalum.[4] Very recently\, we have developed an uncatalysed synthetic pathway to generate the doubly base stabilised symmetrical and unsymmetrical diborane(4) species from the thermolysis reaction of 2-mercaptopyridine with [BH3.THF]. The key results of this work will be described.
