Abstract
The bimolecular systems Fe(bpy)/sub 2/(CN)/sub 2/ and Co(bpy) (PEt/sub 2/Ph)/sub 2/H/sub 2//sup +/ (where bpy = 2,2'-bipyridine and PEt/sub 2/Ph = diethylphenylphosphine) was studied in order to probe the thermodynamic and kinetic constraints of the energy transfer process. Two peaks occur in the spectrum of the complex at 435 and 346 nm. The former peak is proposed as the lowest spin-allowed ligand field transition with a large intensity contribution from the adjacent charge-transfer band, while the 346 nm peak is assumed to be a metal-to-ligand charge-transfer transition involving the Co(III) and either the phosphine of the bipyridine ligand. Irradiation at 436 nm of the complex results in the production of H/sub 2/ with a quantum yield of 0.1 mol/einstein. 17 references, 2 figures, 1 table.
