Photochemistry and Photophysics of Coordination Compounds of the Main Group Metals

Abstract

The photoproperties of main group metal complexes with the electron configurations s2 (e.g. T l + , Sb3 + , Te4 + ) and s° (e.g. T l 3 + , Pb4 + ) were studied on the basis of a general concept which relates characteristic excited states to typical photophysical and photochemical processes. The photochemistry is dominated by metalcentered sp (s2) and ligand to metal charge transfer (s°) excited states which are capable of inducing inter- and intramolecular redox reactions
