    摘要: The synthesis of a nonlinear chromophoric co-monomer 3,5-diamino-4'-nitrodiphenylamine and use as a reactive component in combination with a bismaleimide monomer in a NLO-active polyimide matrix is disclosed. After concurrent corona or contact poling and thermal polymerization, thin films of these chromophoric polyimides exhibit high second harmonic generation efficiencies and high DSC-determined glass transition temperatures. These poled polyimides also exhibit excellent SHG temporal stability, retaining 85-90% of the initial second harmonic efficiency after more than one month in air at 85.degree. C.
