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.
一种呈现磷光-荧光双发射的无金属有机咔唑-嘧啶染料被开发成一种白光发射切换系统。通过打破分子对称性获得的两种晶体多晶型物对加热、蒸汽熏蒸和机械研磨等外部刺激做出响应，形成了一个包括白光发射的三色切换系统。
