为了研究氢键作用对聚联乙炔超分子颜色转变的影响，通过将羧基取代的（邻、Meta、帕拉）苯胺基团与典型的单链联乙炔脂质偶联，合成了具有不同氢键状态的新型联乙炔衍生物.一个在Meta位具有末端羧基的分子提供了具有增强的氢键的超分子朗缪尔-舍费尔膜，因此在热和pH刺激下都产生了前所未有的比色可逆性。
To investigate the role of hydrogen-bonding on colorimetric transition of polydiacetylene supramolecules, novel diacetylene derivatives allowing various hydrogen-bonding states were synthesized by coupling carboxy-substituted (ortho-, meta-, and para-) anilide groups with a typical single-chain diacetylene lipid. One with a terminal carboxyl group at the meta position provided the resulting supramolecular Langmuir−Schaefer films with enhanced hydrogen-bonding, and hence resulted in unprecedented colorimetric reversibility under both thermal and pH stimuli.
