%X 本文设计合成了一种具有聚集诱导效应的苯基吡啶基丙烯腈衍生物(PPAD)作为客体分子&#65292;通过与羧酸盐修饰的水溶性柱[5]芳烃(P[5]A)进行主&#8211;客体作用&#65292;在水中形成了超分子两亲体&#65292;并自组装成P[5]A-PPAD超分子纳米颗粒。由于P[5]A-PPAD具有明显的荧光发射能力&#65292;可将其作为能量供体&#65292;并对能量受体荧光染料4,7-二(2-噻吩基)-2,1,3-苯并噻二唑(DBT)进行包载&#65292;成功构筑了一种新型P[5]A-PPAD-DBT超分子人工光捕获体系。通过性能测试发现&#65292;P[5]A-PPAD-DBT体系的能量转移效率为52.7%&#65292;天线效应为11.6&#65292;具有良好的水相人工光捕获能力&#65292;为水相人工光捕获体系的构筑与发展提供了新的思路。<br>In this work, a phenylpyridinylacrylonitrile-based derivative (PPAD) with aggregation inducing effect was initially designed and synthesized, which was used as a guest molecule. Through host-guest interaction with a water-soluble pillar[5]arene (P[5]A) modified with carboxylate salts, P[5]A-PPAD supramolecular amphiphilics were formed in water and self-assembled into P[5]A-PPAD supramolecular nanoparticles. Due to the significant fluorescence emission ability of P[5]A-PPAD, P[5]A-PPAD could be used as an energy donor and encapsulate the energy acceptor fluorescent dye 4,7-di(2-thienyl)-2,1,3-benzothiadiazole (DBT) to construct P[5]A-PPAD-DBT supramolecular artificial light harvesting system. After further investigation of light-harvesting performance, the energy transfer efficiency of P[5]A-PPAD-DBT system was 52.7%, and the antenna effect was 11.6, which indicated a good aqueous light-harvesting ability, providing new ideas for the construction and development of supramolecular artificial light harvesting systems.
