Abstract : Much of the research effort of this group and others has been devoted to the study of the excited state properties and the redox chemistry of polypyridyl complexes of Ru(II), Os(II) and Re(I) transition metal ions in solution. As a consequence, well developed synthetic procedures exist for the preparation of a variety of these complexes and a wealth of information is available regarding the properties of this interesting class of molecules. The crux of this research proposal was to carry out an in-depth study based on attaching these complexes to solid supports in an attempt to extend their versatility. The formation and characterization of structurally well defined arrays of redox or photoactive molecules on insulating or semiconductor substrates is an important element in the design of molecular-level devices. Any potential device applications however, had to be preceded by addressing the more fundamental questions of how to form stable monolayers of molecules at the solid support and, what effect would this constrained environment have on the fundamental photophysical and redox properties of the molecules. jg p.4
