Abstract

The photophysical and electron transfer properties of the lowest excited state of nine ruthenium (polypyridine) complexes have been characterized. The complexes studied are Ru (bpy)~3‐n~ (LL)^2+^~n~, where n varies from 0 to 3, and LL is 4, 4′‐di‐t‐butyl‐2,2′‐bipyridine (DTB‐bpy), 3, 3′‐dimethyl‐2, 2′‐bipyridine (DM‐bpy), or a 2, 2′‐diquinolyl derivative (DMCH). The results obtained show that the Ru (bpy)~2~(DMCH)^2+^ complex is expected to be a more efficient mediator than Ru (bpy)^2+^~3~ in the water‐splitting reaction by solar energy.
