A new family of organometallic/inorganic nanohybrid Langmuir–Blodgett (LB) films consisting of rigid-rod organomercury acetylide complex (OMA) as the π-conjugated organometallic composite and heteropolyacid salts MPA (MPA = K3PMo12O40, K5BW12O40, Na5IMo6O62) of the Keggin and Anderson structures as the inorganic composite, were prepared and characterized by π−A isotherms, UV−Vis absorption spectra, fluorescence spectra, scanning tunneling microscopy, atomic force microscopy imaging and low-angle X-ray diffraction. Our experimental results indicate that steady Langmuir and LB films are formed in pure water and heteropolyacid salt subphases. Luminescence spectra of hybrid LB films show that MPA can quench the emission of OMA to some extent. These alkynylmercury(II) based LB films display interesting electrical conductivity behavior. They all show decent electrical conductivity, and the tunneling current amounts to ±100 nA when the voltage is set at ±3 ∼ ±5 V.
A new class of luminescent organometallic/inorganic nanohybrid Langmuir–Blodgett films based on a dimercury(II) diacetylide complex were prepared and characterized by π−Α isotherms, low-angle X-ray diffraction, atomic force microscopy and scanning tunneling microscopy. These hybrid composites display intriguing luminescent and electrical properties and have great potential for various optoelectronic applications.Figure optionsDownload as PowerPoint slide
