The present invention relates to 1,3,5-tricyano-2,4,6-tris(vinyl)benzene derivatives and method for preparing the same. The 1,3,5-tricyano-2,4,6-tris(vinyl)benzene derivatives can be prepared by refluxing 1,3,5-tricyanomesitylene with N-formylamine dimethylacetal or substituted benzaldehyde, or by the Wittig reaction of 1,3,5-tricyano-2,4,6-tris[(diethoxyphosphoryl)methyl]benzene with substituted benzaldehyde. The 1,3,5-tricyano-2,4,6-tris(vinyl)benzene derivatives exhibit large first hyperpolarizability in solution and significant second harmonic generation (SHG) in the powder state, and are useful as optical devices such as electro-optic modulators, optical switch, or the like for treating optical signal in optical communication industry.
本发明涉及1,3,5-三氰基-2,4,6-三(乙烯基)苯衍生物及其制备方法。1,3,5-三氰基-2,4,6-三(乙烯基)苯衍生物可以通过将1,3,5-三氰基间苯三甲烷与N-甲酰基二甲基乙烯醇胺或取代苯甲醛回流反应制备,或通过1,3,5-三氰基-2,4,6-三[(二乙氧基膦酰基)甲基]苯与取代苯甲醛的Wittig反应制备。1,3,5-三氰基-2,4,6-三(乙烯基)苯衍生物在溶液中表现出大的第一超极化率,并在粉末状态下表现出显著的二次谐波产生(SHG),可用作光学器件,如电光调制器、光开关等,用于处理光通信行业中的光信号。
