PHOTOCHEMISTRY AND PHOTOPHYSICS OF COORDINATION-COMPOUNDS OF THE MAIN GROUP-METALS

The photoproperties of main group metal complexes with the electron configurations s2 (e.g. Tl+, Sb3+, Te4+) and s0 (e.g. Tl3+, 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 metal-centered sp (s2) and ligand to metal charge transfer (s0) excited states which are capable of inducing inter- and intramolecular redox reactions.
