摘要

By covalently binding chromophore NPP

N-(4-nitrophenyl)-(L)-prolinol

to a structurallycontrolled cage-like cross-linking polymer (SCCP)

a modified nonlinear optical (NLO) polymeric filmprepared by "in situ poling and sol-gel" process successfully overcame the fundamental problem of NPPchromophores subliming out from the cages of the "doped" NLO polymeric film when heated or placed underUV light. Its d33 (coefficient of second harmonic generation) is 2.0×10-8 esu. measured by IR dichroism. The modified film has a low decay of the SHG signal and preserves 94% of the initial value after 50 days at room temperature.These properties match that of the "doped"film

indicating that the modified film also retains the main advantages of the "doped" film.
