Abstract

An alkynyl platinum(II) compound of [Pt(CCPy)2(dppe)] (1) was prepared by reaction of [PtCl2(dppe)] and 4-ethynylpyridine hydrochloride in the presence of base and CuI (dppe = 1,2-bis(diphenylphosphino)ethane). Single crystal X-ray diffraction analysis reveals that compound 1 crystallizes in a monoclinic system and Cc space group with a = 17.8507(7), b = 21.4219(7), c = 9.0526(5) A, β = 108.98(2)°. Thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD), UV-vis spectra, photoluminescence, and catalysis properties of 1 are discussed. The multilayer films formed with ruthenium trichloride by a layer-by-layer self-assembly method were characterized by UV-vis spectra, atomic force microscopy (AFM) images and cyclic voltammograms (CV).
