A series of chromophores with high second-order nonlinearities has been synthesized; the chromphores consist of triarylamine or dialkylarylamine donors linked by a conformationally locked polyene bridge to a dicyanomethylidene acceptor. The use of bridges of this type, combined with the replacement of dialkylarylamine with triarylamine donors, leads to high thermal stability without adverse affects on the nonlinear optical properties of the chromophores.
合成了一系列具有高二阶非线性的发色团;发色团由三芳胺或二烷基芳胺供体组成,通过构象锁定多烯桥与二氰基亚甲基受体连接。这种类型的桥的使用,与用三芳胺供体取代二烷基芳胺相结合,导致了高热稳定性,而不会对发色团的非线性光学性质产生不利影响。
