An efficient artificial light-harvesting system is fabricated from a cyclic polysaccharide, sulfato-β-cyclodextrin (SCD); an aggregation-induced emission molecule, an oligo(phenylenevinylene) derivative (OPV-I); and a fluorescent dye, nile red (NiR), via noncovalent interactions in an aqueous solution. In this system, the OPV-I/SCD supramolecular assembly acts as a donor, and NiR that is loaded into the OPV-I/SCD assembly acts as an acceptor. Significantly, an efficient energy-transfer process occurs between the OPV-I/SCD assembly and the loaded NiR, leading to an extremely high antenna effect.
一种高效的人工光捕获系统是由环状多糖硫酸酯-β-环糊精（SCD）；聚集诱导发射分子，寡聚（苯乙烯基）衍生物（OPV-I）；以及荧光染料尼罗红（NiR）通过非共价相互作用在水溶液中制备的。在该体系中，OPV-I/SCD 超分子组装体作为给体，负载在 OPV-I/SCD 组装体中的 NiR 作为受体。重要的是，OPV-I/SCD 组装体与负载的 NiR 之间发生了有效的能量转移过程，导致了极高的天线效应。
