摘要：

Viologen-linked ruthenium(II) complexes with different methylene chain length between ruthenium complex and viologen, Ru(bpy)(2)(dcbpy)CnVCH3 (n = 2-3), were synthesized and characterized by using spectroscopic techniques. From luminescence spectra, the photoexcited state of Ru(bpy)(2)(dcbpy) is oxidatively quenched by binding viologen, and an intramolecular electron transfer occurs. Ru(bpy)(2)(dcbpy)CnVCH3 were applied for the photoinduced hydrogen evolution in the system containing nicotinamide-adenine dinucleotide phosphate (reduced form, NADPH), Ru(bpy)(2)(dcbpy)CnVCH3 and hydrogenase under steady state irradiation.
