Application of the nonlinear optical materials to the optical and optoelectronic devices requires large second-order nonlinear optical property and thermal stability. 1,2 Much effort has been focused to optimize the physical properties of the donor -acceptor dipoles in order to meet these criteria. While there has been a great progress in improving these properties, it has become apparent that the
非线性光学材料在光学和光电器件中的应用需要大的二阶非线性光学特性和热稳定性。1,2 为了满足这些标准,已经集中精力优化供体 - 受体偶极子的物理特性。虽然在改善这些特性方面取得了很大进展,但很明显偶极分子具有某些局限性。一个这样的问题是与在固态中非中心对称地对齐偶极子以实现最大体积效应相关的困难 [ø(2)]。因为偶极子有利于固态中的反平行配对以消除体积非线性,所以各种方法包括结晶、极化聚合物、Langmuir-Blodgett 膜、和自组装技术已被用来克服偶极子之间的吸引力。3 最近,Dalton 和 Steier 报告说,基于偶极子的聚合物可以制造成具有巨大带宽接受度和低调制电压的电光调制器,这是该领域的重大突破。1
