Abstract:

The primary objective was to quantify the excited states of metal complexes so that their ultimate roles in photophysical, photochemical, and chemical processes could be assessed. The long-term goal was to arrive at a degree of sophistication such that materials with desired electrooptical properties could be designed at a molecular level and synthesized. A comprehensive study of osmiumII 5d6 complexes of D3 symmetry containing N-heterocyclic ligans was completed. The effect of solvents on the interactions of charge-transfer and ligand-field excited states was also quantified. A new series of complexes containing nd10 n 3,4 filled-shell metal ions was synthesized and studied spectroscopically revealing a new type of low-lying excited state. The structure of a typical example of this class of substances was determined by crystallography. A major accomplishment was the development of a multiple-state model for the lowest excited states of nd8 complexes, which was applied to several examples of rhodiumI and iridiumI complexes. Compounds of rutheniumII with N-heterocyclic tridentate ligands and D2d symmetry were also quantified spectroscopically.
