Abstract

The laser flash photolysis of material 1 (layered gamma-ZrP containing covalently attached Ru(bpy)(3)- and C60-phosphonates), dyad 2, and material 3 (amorphous solid Zr(n-BuO) derivative of dyad 2) was accomplished. Zirconium salts, regardless of their amorphous or layered structures, appear to be excellent hosts for developing long-lived charge-separated states between C60 and Ru(bpy)(3) derivatives. Moreover, the presented evidence points to the important fact that the inorganic scaffolding acted as a semiconductor, harvesting the electrons and/or holes produced at the active organic components. These findings suggest that the studied materials could be suitable for the building of practical solar cells.
