Coordination compounds, photochemistry

One of the crucial points in the recent developments of coordination compound photochemistry has been the debate concerning the identity of the excited state(s) responsible for the photosolvation reactions that are obtained by irradiating Cr(III) complexes in their ligand field bands (5,8), Direct photolysis experiments revealed that the most likely candidates (see e.g,. Figures 2 and 3) are the lowest spin-allowed excited state ( T2ff in octahedral symmetry) and the lowest spin-forbidden excited state ( Eg). Such experiments, however, did not warrant any definite conclusion about the actual role of each of these two states (5). 

The special issue of Photochemistry and Photophysics of Coordination Compounds contains two reviews pertinent to Cr(III) systems and another general review coordination compound photochemistry is available. There is also a detailed review of the photophysics of chromium(III) complexes containing an extensive compilation of excited-state relaxation rates. 

Compared with other metal coordination compounds, relatively little is known about chelate photochemistry.

During the last ten years, studies of luminescence and photochemistry of polypyridyl Ru(II), Rh(III) and Co(III) complexes, porphyrins and uranyl salts, in the presence of biological macromolecules such as DNA, have been the focus of increasing research work. The interest in such coordination compounds stems from their easily tunable properties. Not only their size and shape but also their...
