摘要：
An alkoxysilane precursor based on imidazole chromophore, namely 2-((4-(ethyl(2-hydroxyethyl)amino) phenyl)diazenyl)-4,5-dicyano-1H-imidazole (IZ), has been successfully synthesized through a urethane forming reaction. Following a sol-gel process of the resultant precursor, inorganic-organic hybrid films were obtained by spin-coating. Their structures were verified by H-1 NMR, FT-IR, UV-vis spectra and elemental analysis. After corona poling, the electro-optic (EO) properties of the hybrid films were characterized by a simple reflection technique, and the EO coefficient (r(33)) of a sample was determined to be 1.6 pm/V at a wavelength of 1310 nm.
