基于水溶性柱[6]芳烃（WP6）、水杨醛吖嗪衍生物（G）和两种不同荧光染料尼罗红（NiR）或曙红Y（ESY）的超分子自组装，在水溶液中成功制造了高效的光捕获系统。 WP6-G 超分子组装体表现出显着改善的聚集诱导发射增强，并充当人工光捕获系统的供体，而装载在 WP6-G 组装体中的 NiR 或 ESY 充当受体。对于这两个不同的系统，从 WP6-G 组件到 NiR 以及到 ESY 都发生高效的能量传输过程。此外，WP6-G-NiR 和 WP6-G-ESY 系统在高施主/受主比下均表现出超高天线效应。
Highly efficient light-harvesting systems were successfully fabricated in aqueous solution based on the supramolecular self-assembly of a water-soluble pillar[6]arene (WP6), a salicylaldehyde azine derivative (G), and two different fluorescence dyes, Nile Red (NiR) or EosinY (ESY). The WP6-G supramolecular assembly exhibits remarkably improved aggregation-induced emission enhancement and acts as a donor for the artificial light-harvesting system, and NiR or ESY, which are loaded within the WP6-G assembly, act as acceptors. An efficient energy-transfer process takes place from the WP6-G assembly not only to NiR but also to ESY for these two different systems. Furthermore, both of the WP6-G-NiR and WP6-G-ESY systems show an ultrahigh antenna effect at a high donor/acceptor ratio.
