摘要：As we all know, the photosensitizer is the vital role in photocatalytic water oxidation system. In this paper, a novel [Ru(bpY)(2)(tpphz)](PF6)(2) complex (PS1) was synthesized and characterized fully. And, it displayed a higher photoactivity (TON, 110) than [Ru(bpy)(3)](PF6)(2) (PS2) (TON, 62) and [Ru(bpy)(2)(dcb)](PF6)(2) (PS3) (TON, 82) for water oxidation in a three-component system with Ru(bda)(isoq)(2) as catalyst. The main reason for the enhancement of photocatalytic activity should be that the pi-pi stacking supramolecular interaction between the pi-tpphz ligand of the PSI and the pi-isoq ligand of the catalyst increased the intermolecular interaction between PS1 and catalyst, and promoted the molecular aggregation and accelerated valid electronic transmission. Nevertheless, a modest driving force of PSI for photocatalysis water oxidation should be another contribution. (C) 2017 Published by Elsevier B.V.
