Abstract

A new family of organometallic/inorganic hybrid Langmuir-Blodgett (LB) films, consisting of rigid-rod alkynylplatinum(II)-zinc(II) porphyrinate complex (OMA) as the π-conjugated donor-acceptor-type molecule, molybdophosphoric heteropolyacid and heteropolyacid salt (POM = H₃PMo₁₂O₄₀, Na₅IMo₆O₂₄, abbreviated as HPMo₁₂ and NaIMo₆, respectively) of the Keggin and Anderson structures as the inorganic composite, were prepared and characterized by π-A isotherms, UV-vis absorption and luminescence spectra, scanning tunneling microscopy and surface photovoltage spectroscopy. Our experimental results indicate that stable, well-defined and well-organized Langmuir and LB films have been formed in pure water and POM subphase. Luminescence spectra of these hybrid LB films show that HPMo₁₂ can increase the emission intensity of OMA to some extent. These LB composites show good photovoltage responses and a photovoltage of 11. 1 μV can be obtained for the OMA/HPMo₁₂ system when it is excited by light. The 3-layer LB films on ITO wafer can also display intriguing electrical conductivity behavior and the tunneling current amounts to ±100 nA when the voltage is set at -0. 7-2. 5 and -1. 3-0. 8 V for OMA/HPMo₁₂ and OMA/NaIMo₆ hybrid LB films, respectively.
