N2 - The fabrication of a zinc-porphyrin(ZnP)-viologen(V) linked compound with six methylene group (ZnP(6)V)-silver nanoparticle (AgP) composite films on indium-tin-oxide (ITO) electrodes were carried out by the electrostatic layer-by-layer adsorption technique. The photocurrents in ZnP(6)V-AgP 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-AgP composite films are most likely ascribed to the combination of localized surface plasmon resonance due to AgP and photoinduced intramolecular electron-transfer due to the linking of V moiety.
