The derivatization of a polydiacetylene (PDA) polymer with free hydroxyl groups containing sugars leads to amphiphilicity of the polymer and the emergence of thermotropic liquid crystalline behavior, in addition to the thermochromatic properties. The diacetylene monomers, incorporated with mono‐ and disaccharides, exhibit mono‐ and/or enantiotropic phase behavior in a wide temperature range. Structural characterization and modeling studies reveal a lamellar arrangement and interdigitization of the molecules in the mesophase. The importance of the amphiphilicity as a source to induce mesomorphic behavior in PDA polymers is emphasized.

介晶糖衣聚二乙炔聚合物

除具有热色性质外，具有含游离羟基的糖类的聚二乙炔（PDA）聚合物的衍生化还导致聚合物的两亲性和热致液晶行为的出现。与单糖和双糖结合的二乙炔单体在很宽的温度范围内表现出单相和/或对映相行为。结构表征和建模研究揭示了中间相中分子的层状排列和叉指化。强调了两亲性作为在PDA聚合物中引起介晶行为的来源的重要性。
