Photoredox Reaction of [Hg(cyclam)|2+[Co(CO)4r Induced by Outer Sphere Charge Transfer Excitation
Photoredox processes induced by metal-tometal charge transfer (MMCT) excitation have a t tracted much attention in recent years [1-4]. These processes may be exploited for applications in arti ficial photosynthesis and photocatalysis [5, 6], They also facilitate our understanding of optical and thermal electron transfer in general [7, 8], A point of particular interest is the relationship be...
متن کاملPhotoredox Decomposition of [Cobalamin-^-NC-Fen(CN)5]3* Induced by Metal-to-Metal Charge Transfer Excitation
In the presence of oxygen aqueous solutions of the binuclear complex [cobalamin-^-NCFe(CN)5]3' undergo a redox photolysis (0 ~ 2 x 10'3 at Airr = 405 nm) which yields aquocobalamin and [Fe(CN)6]3\ It is suggested that this photoreaction is induced by direct metal-tometal charge transfer (MMCT) excitation. On the contrary, [cobalamin-fx-NC-Ru(CN)5]3' is photo-inert because a reactive MMCT state ...

متن کاملPhotoredox Reactions of Hg(CN)2/[Fe(CN)6]4 and [HgCo2(CN)10]6 Induced by Inner-Sphere Metal to Metal Charge Transfer Excitation
In com plexes o f the type [(NC )2H gIIN C FeII(CN )5]4~ which are formed in aqueous mixtures of H g(C N )2 and [Fe(C N )6]4~ both metals are weakly coupled. Optical metal to metal charge transfer (M M CT) excitation from F e11 to Hg" leads to the reduction of Hg" to Hg" an the oxidation of [Fe(C N )6]4~ to [Fe(C N )6]3~. In the complex [(NC)5CoIH g IIC o I(CN )5]6" the metals are strongly coup...
متن کاملPhotochemistry of Transition Metal Complexes Induced by Outer-Sphere Charge Transfer Excitation
The intermolecular (outer sphere, OS) interaction of a reducing and an oxidizing metal complex generates a new optical transition involving charge transfer (CT) from the electron donor to the acceptor. OS C T transitions are classified according to the redox site (metal or ligand). Generally, the interaction between donor and acceptor is facilitated by ion pairs consisting of an oxidizing compl...
