摘要：

A new cross-linkable polyimide with an NLO chromophore covalently incorporated for second-order optical nonlinearities has been developed. The prepolymer exhibited good solubility in common organic solvents, permitting processing relevant to device fabrication. Optical-quality films were obtained, efficiently poled, cross-linked and imidized. The lattice hardening due to cross-linking and imidization resulted in good stability of the poling-induced order at elevated temperatures. The second harmonic generation signal exhibited dynamic stability up to 160 degrees C and a d(33) coefficient of 70 pm/V.
