“Tuning the Excitonic Properties of 2-Dimensional Molecular Aggregates across the Visible and Shortwave Infrared” Molecular aggregates are non-covalent self-assemblies of chromophores wherein transition dipole moments of individual molecules couple coherently over long distances, forming delocalized excitons. This imparts exciting photophysical properties such as extreme blue or red shifts (seen in H- or J-aggregates respectively), narrow […]
“Invention of Catalysts for Synthesis of New Plastics” Abstract: This presentation will begin with a brief discussion of the properties of polyethylene and the synthesis of various forms of polyethylene via early metal catalysts and via free radical processes. Following this short discussion, I will discuss our thought processes in developing late metal olefin polymerization […]
“f-Block metal-arene interactions: from inverse sandwiches to redox chemistry” Abstract: Recent years have witnessed the breakthrough of identifying unusual oxidation states of f-block elements in molecular compounds such as divalent rare earth metals and actinides, as well as tetravalent terbium and praseodymium. By taking advantage of the symmetry and energy match between the f/d orbitals […]

“Earth-Abundant Molecular Catalyst System for the Reduction of Dioxygen and Carbon Dioxide” Abstract: The steady increase in anthropogenic carbon dioxide (CO2) emissions and corresponding atmospheric concentrations continues to generate interest in using CO2 as a liquid fuel and commodity chemical precursor. The conversion of CO2 has the dual benefit of addressing its associated negative environmental […]
"Scanning probe microscopy for physical and chemical property characterizations at the nanoscale"
The NSF Center for Integrated Catalysis is delighted to announce that it will be hosting a monthly webinar series. The next webinar of this series will be held on Tuesday, April 13th, 2021 at 1:00 PM. We are pleased to invite all students, postdocs, faculty, and staff.
Abstract: Perfluorocarbon nanoemulsions, droplets of fluorous solvent stabilized by a polymeric amphiphile dispersed in water, are an intriguing platform for drug delivery. The fluorous phase is biocompatible, has a high dissolved oxygen content, and is both lipophobic and hydrophobic, preventing the leaching of payloads. Here, we describe the use of perfluorocarbon nanoemulsions as a drug […]
The UCLA Molecular Biology Institute (MBI) will hold the 2020-2021 Sigman Symposium in honor of Professor David Sigman (1939-2001), who was an internationally renowned UCLA professor of chemistry and biological chemistry who illuminated the molecular mechanisms by which enzymes catalyze biological reactions and was one of the founding members of the MBI. 2020-2021 Sigman Award Honoree: […]
Abstract: This lecture will describe some recent developments in the area of electrophotocatalysis, with a particular focus on a trisaminocyclopropenium (TAC) ion catalyst developed by our group.
