Relying on the supramolecular self-assembly of twisted cucurbit[14]urils (tQ[14]), anthracene derivatives (ADPy), Nile red (NiR), and rhodamine B (RB), highly efficient light-harvesting systems have been successfully designed in an aqueous medium. The addition of tQ[14] causes ADPy to aggregate through supramolecular self-assembly to form a supramolecular polymer (ADPy@tQ[14]) with excellent aggregation-induced fluorescence and an interesting spherical external morphology, making it a remarkable energy donor. Consequently, efficient energy-transfer processes have occurred between ADPy@tQ[14] assembly and NiR and RB, which both serve as effective energy acceptors while being loaded onto ADPy@tQ[14]. In the case of NiR, the energy-transfer efficiency is up to 72.45%, and the antenna effect is near 55.4 at a donor/acceptor ratio of 100:1, making it close to the light-harvesting systems in nature. As a result, effective water-soluble artificial light-harvesting systems are showing enormous prospective as versatile platforms for simulating photosynthesis.

基于扭曲葫芦[14]Uril在水溶液中构建的高效人工光捕获系统
依托葫芦[14]脲（t Q[14]）、蒽衍生物（ADPy）、尼罗红（NiR）和罗丹明B（RB）的超分子自组装，成功研制出高效的集光系统设计在水性介质中。t Q[14]的加入使ADPy通过超分子自组装聚集形成超分子聚合物（ADPy@ t Q[14]），具有优异的聚集诱导荧光和有趣的球形外部形态，使其成为卓越的能量供体. 因此，在 ADPy@ t Q[14] 组件与 NiR 和 RB之间发生了有效的能量转移过程，它们在加载到 ADPy@ t上时都充当有效的能量受体问[14]。在 NiR 的情况下，能量转移效率高达 72.45%，天线效应在 100:1 的施主/受主比下接近 55.4，使其接近自然界的光捕获系统。因此，有效的水溶性人工采光系统作为模拟光合作用的多功能平台显示出巨大的前景。
