Abstract

The fabrication of a zinc-porphyrin(ZnP)-viologen(V) linked compound with six methylene group (ZnP(6)V)-gold nanoparticle (AuP) composite films on indium-tin-oxide (ITO) electrodes were performed by the electrostatic layer-by-layer adsorption technique. The photocurrents in ZnP(6)V-AuP composite films were larger than those in ZnP(6)V films, and were much larger than those in ZnP films as a reference. The large enhancement of the photocurrents in ZnP(6)V-AuP composite films are most likely attributable to the combination of localized surface plasmon resonance due to AuP and photoinduced intramolecular electron-transfer due to the V moiety in the linked compound.
