transitions and phases. The binding of lanthanide- and/or transition metal salts to the ligand containing mesogens results in a transition from a liquid crystalline to an isotropic state. Acyclic diene metathesis of the monomers yielded either oligomers or polymers, dictated by whether the alkene is either terminal or nonterminal, respectively. Both oligomers and polymers exhibit enantiotropic liquid crystalline
已经制备和研究了一系列具有化学响应特性的含液晶配体的单体。这些分子是2,6-双苯并咪唑基吡啶(Bip)配体的功能化衍生物。调整芳族核的尺寸和两对烷基取代基的长度可以制备具有一系列可调节的热液晶转变和相的介晶。镧系元素和/或过渡金属盐与含配体的液晶元的结合导致从液晶态到各向同性态的转变。单体的无环二烯复分解生成低聚物或聚合物,这分别取决于烯烃是末端还是非末端。
