A new single-component photocatalyst for water reduction to H2, dichloro(dpbpy)platinum(II) derivative (dpbpy = 4,4’-diphenyl-2,2’-bipyridine) tethered to four pendant viologen acceptors (1), is shown to exhibit higher photocatalytic activity than the previously reported dichrolo(bpy)-platinum(II) analog (2; bpy = 2,2’-bipyridine). The activity of 1 is observed to be twice as high as that of 2, consistent with the higher absorptivity of 1 at the metal-to-ligand charge transfer (1MLCT) band due to the larger π-conjugation in dpbpy relative to bpy.
