将一种具有磷光-荧光双发射特性的无金属有机咔唑-嘧啶染料发展成白光发射开关体系。通过破坏分子对称性获得的两种晶型对加热、蒸气熏蒸和机械研磨的外部刺激做出反应，导致了包括白光发射的三基色开关系统。
A metal-free organic carbazole-pyrimidine dye exhibiting phosphorescence-fluorescence dual emission was developed into a white-light emission-switching system. The two crystal polymorphs obtained by breaking the molecular symmetry responded to the external stimuli of heating, vapor-fuming, and mechanical grinding, resulting in a tricolor switching system that includes white-light emission.
