Abstract
We report the syntheses of two triethoxysilanes for thin film fabrication. One silane (SGDR 1) contains disperse red 1 (DR 1) which is a second-order nonlinear optical (NLO) active chromophore. The other silane (SGCHC) bears a chalcone derivative. In order to improve the poor temporal stability of second-order NLO effects in the resulting poled sol-gel film, photo-crosslink was induced between the double bonds in chalcone units after mixing SGDR 1 and SGCHC. Under UV exposure, the photocrosslink was studied with UV-visible absorption and IR vibrational spectroscopy. The decaying behavior of the molecular order parameter (A2) after corona poling was investigated using polarized absorption spectroscopy (PAS). Second-order non-linear optical properties of the sample were studied using second-harmonic generation (SHG) and linear electro-optic (E/O) signal measurement. Poled and UV-cured film of SGDR 1/SGCHC exhibited much better stability than thermally poled sample with respect to the molecular order parameter and linear electro-optic effect.
