Abstract

Two layered zirconium phosphates containing Ru(bpy)32+ mono- or diphosphonates and diquat, {Ru(bpy)32+[1]/ZrP/DQ++} and Ru(bpy)32+[2]/ZrP/DQ++, covalently attached to the phosphate layers exhibit notable photovoltaic response (the maximum VOC, JSC, and FF were 0.093 V, 16.8 μA cm−2 and 0.33, respectively). The photocurrent spectra indicate that the photovoltaic response is due predominantly to direct photoexcitation of γ-ZrP host, Ru(bpy)32+ and diquat acting as hole and electron traps, respectively, for the charge separated state of the semiconductor.
