Abstract

We prepared the photorefractive composite based on organic-inorganic hybrid materials containing charge-transporting molecules, second-order nonlinear optical chromophore, photosensitizer, and plasticizer either as a side chain unit or a guest molecule. New chromophore was synthesized to contain nonlinear optical chromophore and carbazole in one molecule. The functional chromophores were reacted to isocyanatotriethoxysilane to provide the functional precursor molecules. 2,4,7-Trinitrofluorenone (TNF) was added into the sol-gel materials to induce a charge-transfer complex. We also compared the gain coefficient of the photorefractive samples with the change of the concentration of the plasticizer, determined by two-beam coupling technique.
