摘　　要：设计合成了一种新型亚水杨基苯胺类客体分子(PPA),通过水溶性柱[5]芳烃(WP5)的诱导组装,成功构筑了WP5■PPA超分子纳米粒子。由于染料分子4,7-双(噻吩-2-基)-2,1,3-苯并噻二唑(DBT)的紫外吸收与WP5■PPA的荧光发射高度重叠,WP5■PPA两亲体在包载DBT后,成功构筑了一种新型的水相WP5■PPA-DBT人工光捕获系统。人工光捕获结果表明其具有70.5%的能量转移效率和32.2的天线效应,在水相人工光捕获系统中具有潜在的应用价值。WP5■PPA nanoparticles were firstly fabricated by the supramolecular assembly of water-soluble pillar[5]arene(WP5)and salicylidene-aniline guest(PPA).Due to the UV absorption of 4,7-bis(thien-2-yl)-2,1,3-benzothiadiazole(DBT)covering well with the emission of WP5■PPA,a novel aqueous artificial light-harvesting system was successfully constructed,which showed the energy transfer efficiency of 70.5%and antenna effect of 32.2,suggesting a potential application in aqueous artificial light-harvesting systems.
