Abstract
We selected polyamic acid as a precusor of polyimide which is highly thermally resistant and disperse red 1 as a nonlinear optical active chromophore. Two compounds that were anchored with trialkoxy silane were employed to fabricate the organic/inorganic composite film via sol-gel process. After corona poling and thermal treatment, partial imidization was completed. Resulting from the network and good thermal resistance, the molecular dipolar alignment became very stable after poling. Therefore, we developed the polyimide analogue with NLO chromophore to exhibit good temporal stability.
