摘要 制备了六(4-羧基苯氧基)环三磷腈(CTPacid)与棒状型咪唑衍生物(I)形成的氢键超分子复合物,并研究了复合物的液晶行为.结果表明,复合物能呈现层列液晶A相(SmA),讨论了烷氧基链的长短,数目对复合物超分子液晶行为的影响. Supramolecular liquid crystalline complexes between hexa(4-carboxylphenoxy) cyclotriphosphazene and rod-like imidazol mesogens through hydrogen bond were prepared.The mesosphere behaviors of such complexes were investigated with POM.Smectic A phases are exhibited by these complexes.The influence of the length and number of the alkoxy chains on the mesosphere behaviors is discussed.
