Structural Electronic Relationships in Polymeric Solids.

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 osmium(II) (5d)6 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 (nd)10 (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 (nd)8 complexes, which was applied to several examples of rhodium(I) and iridium(I) complexes. Compounds of ruthenium(II) with N-heterocyclic tridentate ligands and D2d symmetry were also quantified spectroscopically.
