applications. In this paper, we report that turn-on-type double emission changes and ratiometric emission color changes can be achieved simultaneously by exploiting the aggregation of V-shaped bis(thiadiazolo)quinoxaline- and bis(thiadiazole)phenanthroquinoxaline-triphenylamine donor–acceptor type dyes in aqueous media. When the water fraction of THF/water media in which the dyes were placed was increased, the

水含量增加时,单体态的初始红色发射通过猝灭近红外发射而变为聚集态的橙色发射。这种异常的双发射变化归因于聚集和扭曲的分子内电荷转移的联合作用。
