We report a general design strategy for a new class of luminogens with dual-state emission (DSEgens) that are brightly emissive in both the solution and solid state, with solvatochromism properties, by constructing a partially shared donor-acceptor pattern based on a twisted molecule. The DSEgens with bright fluorescence emission in both the solid and solution state demonstrate a unique solvatochromism behaviour depending on solvent polarity and thus may have applications in anti-counterfeiting.
我们报道了一种新型双态发光体（DSEgens）的通用设计策略，通过基于扭曲分子构建部分共享的供体-受体模式，使其在溶液和固态中均能发出明亮的光，并具有溶剂化显色特性。在固态和溶液状态下均具有明亮荧光发射的DSEgens，根据溶剂极性表现出独特的溶剂化显色行为，因此可能在防伪方面有应用。
