Biography

Experience
The University of Alabama at Birmingham
Professor of Chemistry
I teach the two General Chemistry Honors courses and the junior and senior Inorganic Chemistry courses each year. I also teach graduate courses in Transition Metal Organometallic Chemistry, Small Molecule X-ray Crystallography and NMR spectroscopy as needed.
My research is focused in two areas. The first involves metallacrown ethers, which are complexes formed by the chelation of alpha,omega-bis(P-donor)polyether ligands to transition metals. These complexes are of interest because they are capable of binding cations and small molecules. Such binding could allow them to be used as sensor elements and as catalyst for reactions such as alkene hydroformylation.
My second research area is the development of third-order nonlinear optical materials for sensor protection. Current materials of interest are molecular and polymeric compounds containing phosphine- or phosphonate-substituted oligothiophenes. The phosphine-substituted bithiophenes exhibit the best nonlinear absorption in the blue-violet region of the visible spectrum that has been reported to date. Some of these molecules also exhibit fluroescence in the blue-violet region of the visible spectrum and could have applications in organic light emitting diodes.J. T. Baker Chemical Co.

Publications
Multinuclear NMR Spectroscopic and X-ray Crystallographic Studies of Electronic and Steric Effects of Phosphonous Acid Ligands and Their Chlorophosphite Ligand Precursors in Tungsten Pentacarbonyl Complexes
European Journal of Inorganic Chemistry
To gain insight into the electronic and steric properties of phosphonous acid ligands, we have prepared tungsten(0) pentacarbonyl complexes with chlorophosphite ligands derived from either 2,2′-biphenol or (±)-1,1′-bi-2-naphthol and have then hydrolyzed the coordinated ligands to generate tungsten(0) pentacarbonyl complexes with the corresponding phosphonous acid ligands. NMR measurements of the W–P coupling constants demonstrate that changing the biaryl groups from biphenyl to binaphthyl does not affect the electron-donor ability of the ligand, whereas changing the third substituent from chloro to oxo has a significant effect. Estimation of cone angles of the ligands from X-ray crystallographic data have shown that neither changing the biaryl group nor changing the third substituent have a significant effect on their cone angles. Further, these studies have identified important intra- and intermolecular interactions that favor certain ligand conformations.
