| 抄録: | Organized composite molecular nanoassemblies of fullerene and poly[2-methoxy-5-(2'-ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) prepared in acetonitrile/toluene mixed solvent absorb light over the entire spectrum of visible light. The highly colored composite clusters can be assembled as a 3 dimensional array onto nanostructured SnO_2 films by electrophoretic deposition approach. The composite cluster films exhibit an incident photon-to-photocurrent efficiency (IPCE) as high as 18%, which is significantly higher than that of a molecular assembly composed of 5,10,15,20-tetrakis(3,5-di-tert-butylphenyl)-21H,23H-porphyrin (H_2P) and C_<60> prepared in the same manner (4%). The maximum IPCE value increases to 25% under an applied bias potential of 0.2 V vs. SCE. The power conversion efficiency of MEH-PPV and C_<60> assembly-modified electrode is determined as 0.24%. The photocurrent generation properties observed with MEH-PPV and C_<60> clusters demonstrate the synergy of these systems towards yielding efficient photoinduced charge separation within these composite nanoclusters. |
