Abstract
With the aid of rational design, we have synthesized a pair of water-soluble donor- and acceptor-type twisted perylene bisimide units, which together form aggregates upon lowering the pH of the medium, providing bright yellow fluorescence. The light-harvesting efficiency of the co-assembled system can be tuned by controlling the ratio of donor to acceptor and 98.1 % efficiency has been achieved.
摘要
借助合理的设计，我们合成了一对水溶性给体-受体型扭曲的苝二酰亚胺单元，它们在降低介质 pH 值时会聚集在一起，发出亮黄色荧光。通过控制给体与受体的比例，可以调节共组装体系的光收集效率，实现了 98.1%的高效率。
