Assoc. Prof. William HeuerOverview: Synthetic inorganic chemistry. Preparation and study of metal complexes with interesting photophysical and redox properties. Characterization by NMR, IR, UV-Vis, Luminecence, MALDI-MS, Cyclic Voltammetry, X-Ray diffraction (with Prof. Pearson).

Active projects:•Synthesis and photophysical studies of transition metal complexes with extended a-diimmine-dithiolene ligands for solar cell applications. (Current student: 1/C Doyoung Lee)•Synthesis and characterization of potentially luminescent heteroleptic Pt(II) oxyquinolate complexes.•(Current student: 1/C Delano Martins)

Assoc. Prof. Wayne Pearson

X-ray Crystallographic Studies of Inorganic Systems

Possible Projects:

(1) Applications of cryolite fluxes to crystal growth

(2) Alternative methods of crystal growth and effects upon crystal quality(3) Modeling thermal motion in the solid state(4) Electron density determination using X-ray diffractionCurrent Students: 1/C Percival and 1/C Smith

CDR Doug BrownOverview:

My Ph.D. research was dimolybdenum and ditungsten paddlewheel complexes. The goal of this work is to understand electron transfer processes such as metal-to-ligand charge transfer and electronic communication between dimetal centers when connected by an unconjugated bifunctional bridge. My post-Ph.D. research is the fabrication of nano-rods and particles to examine optical properties through laser spectroscopy. In addition, Ruthenium photo-sensitive complexes have been synthesized to examine their optical dynamics.

My research interests are:1) EXPLORE ALTERNATIVE SYNTHESIS OF INORGANIC

COMPLEXES USING MICROWAVE RXN EQUIPMENT.

2) COPPER-CATALYZED REACTIONS OF ARYL HALIDES USING A CONCURRENT TANDEM CATALYTIC METHODOLOGY

Current students: 1/C MacPherson and 1/C Thompson

Assoc. Prof. Amy MacArthurResearch interests:• development of inexpensive catalysts (Co, Cu, and Ni) to replace traditional, expensive Pd, Pt, Rh, and Ir catalysts

• development of catalytic reactions with two catalysts operating simultaneously in solution (tandem catalysis)
