Title: Energy transformations in organometallic complexes. Progress report, July 1, 1984-September 31, 1985

Abstract

The primary purpose of research projects performed during this report period was to characterize the fundamental photoproperties of a variety of ortho-metalated species. The proposal which was submitted and approved in 1984 describes our initial work on dichloro-bridged dimeric complexes of Ir(III) and Rh(III) with 2-phenylpyridine (ppy) and benzo(h)quinoline (bzq). During 1985 efforts have been expanded to incorporate the additional metal centers, Re(1) and Pd(II), as well as different ortho-metalating ligands including 3-methyl-2-phenylpyridine (mppy), 2-(p-tolylpyridine) (tpy), azobenzene (azb) and 2-phenylpyrimidine (ppyr). In addition, several new, mononuclear complexes of Ir(III) and Rh(III) with various combinations of metallated ppy or bzq and coordinated 2,2'-bipyridine (bpy) or 1,10-phenanthroline (phen) ligands have been prepared and studied. The goals of studies of these complexes are to provide a basis for evaluating their potential application as photocatalysts and to generally provide initial characterizations of the effects of metal-carbon sigma bonds on the identity, photophysics, and photochemistry of their low energy excited states. For purposes of organization the work described in this report is divided into four projects corresponding to the four graduate students who are currently working in this program. 2 figs., 2 tabs.
