Photochemistry of Carbonyl Complexes
The photosensitivity of metal carbonyls has been known almost as long as the class of coordination compounds itself. Among no other group of inorganic compounds may one find so many light-sensitive materials. Hence photochemical reactions of metal carbonyls have found wide applications for synthetic purposes. However, whereas much research has been done to understand the thermal reactions," the...
متن کاملPhotochemistry of Osmium-Carbyne Complexes
Upon charge transfer (Os to carbyne) excitation the carbyne complexes Os(CPh)(CO)(PPh3)2Cl and [Os(CPh)(CO)2(PPh3)2]+ with Ph = C6H5 are converted to the carbene complex Os(CHPh)(CO)(PPh3)2Cl2 in solutions containing HCl. It is suggested that the relaxed CT state can be described as square-pyramidal Os(II) complex containing a bent carbyne ligand which carries a lone pair at the coordinating ca...
متن کاملStructure and Photochemistry of Manganese Porphyrin Sulfate Complexes
New sulfate and hydrogen sulfate complexes of metalloporphyrins have been synthesized and crystallographically characterized and their photochemistry examined. Irradiation of [Mn(TPP)],(SO,) and Mn(TPP)(OS03H) (where TPP = 5,10,15,20-tetraphenylporphyrinate(2-)) produces Mn"(TPP) quantitatively, with quantum yields of 7.1 X IO4 and 9.8 X IO-', respectively. In contrast to other manganese oxoani...
متن کاملThe photochemistry of transition metal complexes using density functional theory.
The use of density functional theory (DFT) and time-dependent DFT (TD-DFT) to study the photochemistry of metal complexes is becoming increasingly important among chemists. Computational methods provide unique information on the electronic nature of excited states and their atomic structure, integrating spectroscopy observations on transient species and excited-state dynamics. In this contribut...
متن کاملThe photochemistry of rhenium(I) tricarbonyl N-heterocyclic carbene complexes.
The photophysical and photochemical properties of the new tricarbonyl rhenium(I) complexes bound to N-heterocyclic carbene ligands (NHC), fac-[Re(CO)3(N^C)X] (N^C = 1-phenyl-3-(2-pyridyl)imidazole or 1-quinolinyl-3-(2-pyridyl)imidazole; X = Cl or Br), are reported. The photophysics of these complexes highlight phosphorescent emission from triplet metal-to-ligand ((3)MLCT) excited states, typica...
