KEITH DeARMOND
B.S. (DePauw) 1958; Professor DeArmond's research concerns unique electronic and magnetic properties of metal chelate systems as [Ru(2,2'-bipyridine)3]2+. The localization of charge resulting form the addition of electrons or the photoexcitation of the species has been characterized by a variety of spectroscopic and electrochemical methods. Professor De Armond's group will exploit some aspects of the charge localization. Photoelectro-chemical measurements at the interface of two liquids may permit efficient generation of photoreduced reagents for solar energy water splitting reactions. Pendant metal complex oligomers with [sigma] electron backbone will be used as charge storage and redox materials while [Pi] electron backbone materials can provide redox conduction and also electronic conduction. Two dimensional ordered molecular films produced by Langmuir-Blodgett methods containing hydrophobic transition metal complexes can provide a new source material for thin films capable of a functional response. This functional response, the concentration variation and the multilayer capability of these films can provide a starting point for molecular electronics devices.
