title: Synthesis and characterization of a novel linear trinuclear ruthenium(II) complex: variation of photosensitization ability with chain length in a homologous series.
abstract: A new, one-step preparation of 1,4-di(2,2':6',2' '-terpyridin-4'-yl)benzene was employed in the synthesis of a linear trinuclear Ru(II) complex, which was compared to mononuclear and dinuclear analogues using UV-vis spectrometry, cyclic voltammetry, and ability to sensitize the photogeneration of methyl viologen radical cation. The chain length-dependent increase in sensitization ability was consistent with an increasing molar absorbance and with an end-on approach of the photoreactants mitigating the increasing charge.
