AbstractThe photoinduced intra-molecular electron transfer in three aniline-containing Ru(II) polypyridine complexes, [Ru(bpy)(2)(bpy-bmam)] (PF6)(2) (2), Ru(dcbpy)(bpy-bmam)(NCS)(2) (3), and Ru(dcbpy)(bpy-mam)(NCS)(2) (4) (bpy-bmam = 4,4'-bis(N-methyl-anilinomethyl)2,2'-bipyridine, bpy-mam = 4-methyl-4'-(N-methyl-anilinomethyl)-2,2'-bipyridine, dcbpy = 4,4'-dicarboxyl-2,2'-bipyridine, bpy = 2,2'-bipyridine), was investigated using steady-state and time-resolved absorption and emission spectra, and photoinduced inter-molecular electron transfer between [Ru(bpy)(2)(dmbpy)](PF6)(2) (1) (dmbpy = 4,4'-dimethyl-2,2'-bipyridine) and N,N-dimethylaniline was also studied for comparison. While inter-molecular reductive quenching of 1's emission by aniline was less efficient, nearly half emission was quenched intra-molecularly in 2. Upon photoinduced electron injection onto the conduction band of TiO2 from 3 or 4 anchored on the TiO2 surface, intra-molecular electron transfer from aniline moiety to Ru(Ill) orbital occurred rapidly with rate constants of 3.4 x 10(7) and 2.6 x 10(7) s(-1), respectively, restricting the interfacial recombination of injected electrons with Ru(III) and as a result improving the photoelectrochemical behavior of 3 or 4 when used in dye-sensitized nanocrystalline semiconductor solar cells.
