%X 本研究基于主客体识别作用构建了一种新型水相光捕获系统。通过水溶性羧酸盐柱[5]芳烃(WCP[5])与咔唑基苯基丙烯腈衍生物(CPTD)在水相中的超分子组装作用&#65292;成功制备了具有荧光特性的纳米组装体(WCP[5]-CPTD)。该纳米结构通过包覆能量受体磺酰罗丹明B(SRB)&#65292;实现了WCP[5]-CPTD-SRB三元光能捕获体系的构筑。实验数据显示&#65292;在供受体摩尔配比优化至125:1的条件下&#65292;体系展现出显著的能量传递性能&#65292;其能量转移效率提升至61.4%&#65292;同时获得11.3的天线效应增益值。这一基于超分子组装策略构建的水相光捕获体系&#65292;为开发高效水相人工光合系统提供了创新性研究范式。<br>This study developed a novel aqueous light-harvesting system based on host-guest molecular recognition. By using the supramolecular assembly between water-soluble carboxylate-pillar[5]arene (WCP[5]) and a carbazolylphenylacrylonitrile derivative (CPTD) in aqueous media, fluorescent nanoassemblies (WCP[5]-CPTD) were successfully constructed. This nanostructure was further functionalized by encapsulating the energy acceptor sulforhodamine B (SRB), establishing a ternary WCP[5]-CPTD-SRB light-harvesting system. Experimental results demonstrated that the system achieved remarkable energy transfer performance, with energy transfer efficiency reaching 61.4% and an antenna effect of 11.3 at an optimized donor-acceptor molar ratio of 125:1. This supramolecular assembly-driving aqueous-phase light-harvesting platform presented an innovative research paradigm for developing efficient artificial photosynthetic systems.
