John,Gladysz,Distinguished Professor,"My research has traditionally been centered around organometallic chemistry, and from this core area branches into catalysis, organic synthesis, enantioselective reactions, stereochemistry, mechanism, and materials chemistry. About half of my group is involved with catalysis projects. Areas receiving emphasis include (a) structurally novel new families of highly enantioselective catalysts, (b) metal-containing ""organocatalysts"" and (c) recoverable catalysts, particularly those with ""ponytails"" of the formula (CH2)m(CF2)nF; these can be recycled via ""fluorous"" liquid or solid phases, such as Teflon. The other half of my group synthesizes organometallic building blocks for molecular devices. These include (a) molecular wires composed of metal endgroups and linear (sp) carbon chains, including stable species with C28 bridges, (b) analogs in which the charge-transmitting bridges are insulated by a pair of polymethylene or (CH2)n chains that adopt a double-helical conformation, (c) polygons and multistranded molecular wires based upon such building blocks, and (d) molecular gyroscopes and compasses consisting of a rotating MLn fragment and an external cage (stator) that insulates the rotator from neighboring molecules, exactly as with the commercial gyroscopes used for aircraft and space-station navigation.",Faculty Affiliate||Distinguished Professor,Energy Institute||Chemistry,https://scholars.library.tamu.edu/vivo/display/n05e5403e
Donald,Darensbourg,Distinguished Professor,"The fundamentally interesting and challenging chemistry associated with carbon dioxide, coupled with its high potential as a source of chemical carbon, provides adequate justification for comprehensive investigations in this area. In our research program we have attempted to establish a clearer mechanistic view of carbon-hydrogen, carbon-carbon, and carbon-oxygen bond forming processes resulting from carbon dioxide insertion into M-H, M-C, and M-O bonds.
Relevant to the latter process our research has addressed the utilization of carbon dioxide in the development of improved synthetic routes for the production of polycarbonates. The hazardous and expensive production process currently in place industrially for these materials involves the interfacial polycondensation of phosgene and diols, accentuates the need for these studies. Although we and others have made significant advances in the synthesis of these useful thermoplastics from carbon dioxide and epoxides much of the fundamental knowledge concerning the reaction kinetics of these processes is lacking, due in part to the practical challenges associated with sampling and analyzing systems at elevated temperatures and pressures. This information is needed for making this process applicable to the synthesis of a variety of copolymers possessing a range of properties and uses. Our studies are examining in detail the mechanistic aspects of metal catalyzed carbon dioxide/epoxide coupling reactions employing in situ spectroscopy methods. For this purpose Fourier-transform infrared attenuated total refluctance (FTIR/ATR) spectroscopy is being utilized. Other related investigations involve the development of structural and reactivity models for the industrially prevalent double metal cyanide catalysts(DMC) used in polyethers and polycarbonate synthesis from epoxides or CO2/epoxides, respectively.",Distinguished Professor||Faculty Affiliate,Energy Institute||Chemistry,https://scholars.library.tamu.edu/vivo/display/n06bf3bf8

Marcetta,Darensbourg,Distinguished Professor,"Bio-inspired Catalysts for Hydrogen Production: The ultimate, home-run, goal of our work is to synthesize and develop a robust, highly active hydrogen-producing catalyst comprised of earth-abundant transition metals within a ligand environment that is inspired by the biological Figure 3hydrogenase (H2ase) enzyme active sites. Progress in precise structural modeling of the illusive ""rotated"" structure displayed in the as-isolated, mixed-valent FeIIFe state in the past decade has permitted in depth analysis of electronic structure by Mo ssbauer, EPR (ENDOR), and computational chemistry. New electrocatalysts for hydrogen production: The connection between the Fe(NO)2 unit and the Fe(CX)3 (X = O or N) unit found in hydrogenase enzyme active sites offers opportunity for design of new catalysts, one of which is shown. In this regard we explore the ability of N2S2 metal complexes to bind as metallodithiolate ligands to various metal acceptors. The properties of such complexes vary The connection of these to light harvesting molecules for dye sensitized, sacrificial electron donor, hydrogen production is also of interest. When Iron Meets Nitric Oxide: Good Chemistry, Intriguing Biology. The affinity of iron for diatomic molecules, O2, CO, N2, and NO, is central to the most important of life processes, including those of human physiology. Figure 6In this research area we target synthetic chemistry involving dinitrosyl iron complexes (DNICs) that serve as biomimetics of products of FeS cluster degradation by excesses of NO, or as derived from the chelatable iron pool (CIP) in cells. The electronic ambivalence of the DNIC unit is expressed in the ease with which it interconverts between oxidized and reduced forms, {Fe(NO)2}9 and {Fe(NO)2}10, respectively (Enemark/Feltham notation), and serves as impetus to explore analogous reactions known to involve the CuII/CuI redox couple.

Matthew,Sheldon,Assistant Professor,"Our research considers fundamental questions of optical energy conversion relating to plasmonic and inorganic nanoscale materials. Our experiments are principally designed to identify and optimize unique nanoscale phenomena useful for solar energy conversion, as well as related opportunities at the intersection of nanophotonics and chemistry. We employ optical and electrical characterization techniques with high spatial and energy resolution to probe optical excitation and relaxation mechanisms in nanostructured metals and semiconductors.
The current world record solar cell operates at 44.4% power conversion efficiency. Thermodynamic analyses indicate that much higher efficiency is theoretically possible. Indeed, technical challenges, rather than laws of nature, limit current solar power convertors from achieving the maximum thermodynamic efficiency of 95%.
We seek to better understand how nanofabricated optoelectronic and plasmonic materials provide a route to achieve the maximum possible conversion efficiency with solid state and photoelectrochemical systems. We explore how nanostructuring materials enables systematic control of the thermodynamic parameters governing optical power conversion, enabling optimization that can shape, confine, and interconvert the energy and entropy of a radiation field. Additionally, the remarkable nanoscale tailorability of a variety of structural properties, such as electrochemical potential, can further enable novel photochemical systems with broad application beyond the scope solar energy conversion.
We seek students who are interested to gain expertise in inorganic synthesis of nanocrystals with tunable electrochemical and optical structures, nanofabrication, and comprehensive characterization and modeling of optoelectronic structures.

Janet,Bluemel,Professor,"Major research interests in my group include (1) immobilized catalysts, (2) the surface chemistry of oxide materials and (3) solid-state NMR spectroscopy.
Immobilized catalysts (1) allow the advantages of heterogeneous catalysts to be combined with those of homogeneous catalysts. In particular, surface-immobilized homogeneous catalysts are easy to recycle, and can be highly active and selective. Furthermore they are amenable to systematic design. We find the most interesting results when heterobimetallic systems, such as the Sonogashira Pd/Cu catalyst for the coupling of aryl halides and terminal alkynes, are involved. Effective immobilization requires a thorough understanding of the surface chemistry of the oxide support materials (2). Therefore, we investigate not only the reactivity of metal complexes and linkers, but also their mobility on the surfaces.
The most powerful analytical tool for investigating amorphous materials is solid-state NMR spectroscopy (3). We optimized this method especially for surface-bound species, enabling us to study reactions on surfaces, or analyze the nature of our anchored linkers and catalysts.
These different research areas provide my students with a strong multidisciplinary background, spanning from synthetic chemistry, through materials sciences and catalysis, to surface analytical methods including solid-state NMR spectroscopy.

David,Bergbreiter,Professor,"Our group explores new chemistry related to catalysis and polymer functionalization using the tools and precepts of synthetic organic chemistry to prepare functional oligomers or polymers that in turn are used to either effect catalysis in a greener, more environmentally benign way or to more efficiently functionalize polymers. Often this involves creatively combining the physiochemical properties of a polymer with the reactivity of a low molecular weight compound to form new materials with new functions. These green chemistry projects involve undamental research both in synthesis and catalysis but has practical aspects because of its relevance to practical problems.
A common theme in our catalysis studies is exploring how soluble polymers can facilitate homogeneous catalysis. Homogeneous catalysts are ubiquitously used to prepare polymers, chemical intermediates, basic chemicals and pharmaceuticals. Such catalysts often use expensive or precious metals or expensive ligands or are used at relatively high catalyst loadings. The products often contain traces of these catalysts or ligands - traces that are undesirable for esthetic reasons or because of the potential toxicity of these impurities. Both the cost of these catalysts of these issues require catalyst/product separation - separations that often are inefficient and lead to chemical waste. These processes also use volatile organic solvents - solvents that have to be recovered and separated. Projects underway in our lab explore how soluble polymers can address each of these problems. Examples of past schemes that achieve this goal in a general way as highlighted in the Figure below.
We also use functional polymers to modify existing polymers. Ongoing projects involve molecular design of additives that can more efficiently modify polymers' physical properties.
