Abstract

Two new nanohybrid 2,5-bis(ferrocenylethynyl)thiophene (BFET)/dimethyldioctadecyl-ammonium (DMDOA)/tungstophosphoric heteropolyacids (HPA, HPA＝H₃PW₁₂O₄₀, H₆P₂W₁₈O₆₂) LB films were prepared and characterized by π-A isotherms, UV-vis absorption spectra, atomic force microscopy, scanning tunneling microscopy, surface photo voltage spectroscopy and fluorescence spectra. The results indicated that the title LB films had the nanosize and quite strong photovoltage response in the visible region. The tunneling current was ±100 nA, when voltage was ±2.0 V.

Key words: polyoxometalate, 2,5-bis(ferrocenylethynyl)thiophene, dimethyldioctadecylammonium, hybrid Langmuir-Blodgett film, photo-electric property
