Sodium lauryl sulfate-ruthenium(II) interactions: Photogalvanic and photophysical behavior of Ru(II)-diimine complexes

The photogalvanic and photophysical behavior of a number of mixed-ligand ruthenium(II) complexes of 2,2′-bipyridine (bpy), 3,3′-bipyridazine (bpd), 2-(2′-pyridyl)quinoline (pyq), 4,4′-dimethyl-2,2′-bipyridine (dmbpy), and 2,3-bis(2′-pyridyl)pyrazine (dpp) is reported both in water and in sodium lauryl sulfate (SDS) solutions. The effect of SDS on the photogalvanic experiment is predominantly an enhancement and/or modification of the photochemical and electrochemical processes. Luminescence, lifetime measurements, and photochemical behavior are affected by SDS and are used to predict possible modes of micelle-complex interactions.
