الوصف: | 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. |
