介绍了几种具有液晶相态特征的功能化梯形聚硅氧烷，包括β－二酮、西夫碱、偶氮３种类型液晶侧链的“鱼骨形”液晶高分子和相应的金属络合型液晶高分子以及挂接发色团的非线性光学梯形高分子。它们是由反应性聚氢基倍半硅氧烷及其共聚物与功能性单体进行硅氢加成反应来合成的。“鱼骨形”液晶高分子与小分子液晶组成高分子网络液晶（ＰＮＬＣ）型的复合物，表现出有趣的正性或负性两种不同的电光响应行为，与“锚泊效应”和弹性有关。非线性光学梯形高分子的极化膜表现了稳定的极化诱导取向。高温下稳定的双折射光带为这类梯形高分子共同的相态特征之一。可控孔径尺寸的笼状自组装超分子膜及其与有机小分子构成的分子级功能复合膜为逐步偶联聚合方法的另一重要发展方向。
Several kinds of functionalized ladder polysiloxanes with phase characteristics of liquid crystal were introduced, including “fishbone” liquid crystal polymer with β-diketone, A type of liquid crystal polymer and a non-linear optical ladder polymer attached to a chromophore. They are synthesized by the hydrosilylation of reactive polyhydrogensilsesquioxanes and their copolymers with functional monomers. The “fish bone” liquid crystal polymer and the small molecule liquid crystal make up the polymer network liquid crystal (PNLC) type complex, exhibiting two positive and negative electro-optic response behaviors of interesting positive and negative, which are related to “anchor effect” and elasticity . Polarizing films of nonlinear optical ladder polymers exhibit stable polarization-induced orientation. Stable birefringence bands at high temperatures are one of the common phase characteristics of this type of ladder polymer. Cage-like self-assembled supramolecular films with controlled pore sizes and molecular-scale functional composite membranes with organic small molecules are another important development direction for the stepwise coupling polymerization.
