Abstract
Three new hybrid LB films consisting of organometallic polymers (OMP) containing conjugated large π bond as organic composite, tungsto(molybdo) phosphoric heteropoly acids (HPA, HPA=PMo12, PW12, P2Mo18) with Keggin and Dawson structure as inorganic composite, and octadecylammonium (ODA) as auxiliary film forming agent were prepared and characterized by π-A isotherms, UV-vis absorption spectra, fluorescence spectra, atomic force microscopy, scanning tunneling microscopy, and surface photovoltage spectroscopy. The experimental results indicate that the collapse pressure of the title nanohybrid LB films was 26.8 mN/m. The fluorescence spectra showed that strong emission of OMP appeared in the films and the title LB films also had strong photoelectric response. Tunneling current was -0.1∼-2.3 nA, when voltage was ±8.0 V.
