摘要：

Novel functionalized second order nonlinear optical (NLO) chromophores have been prepared with functionalized aniline as electron donor, thiophene or isophorone as a pi-spacer and 1,3-diethyl-2-thiobarbituric acid as electron acceptor. The films prepared from dyes with alkylsilyl bulky groups gave better performance than the corresponding non functionalized chromophores due to the reduction of the intermolecular electrostatic interactions. The incorporation of chromophores 4 and 10 in a polycarbonate matrix allowed the preparation of good optical-quality films. Nonlinear coefficients d(33) and d(31) as high as 17 and 5.6 pm V-1, respectively, were obtained. Moreover, the temporal stability of these hostguest films was confirmed up to eight months (>80%).
