Zwitterionic imidazolium 2‐pyridin‐3‐olates exhibit intense blue emission at ambient temperature in the crystalline state, while other analogues such as 2‐phenolate and 3‐pyridin‐2‐olate are less emissive. XRD analyses and DFT calculations revealed that twisting control of arenolate functionalities is the key to obtaining efficient solid‐state fluorescence of the imidazolium–arenolate dyads.

两性离子咪唑鎓吡啶鎓盐的荧光晶体：基于发射性N-芳基咪唑鎓平台的扭曲控制的固态发射的合理设计

两性离子咪唑-2-吡啶-3-醇盐在室温下呈结晶态时会发出强烈的蓝光，而其他类似物（例如2-酚酸酯和3-吡啶-2-醇盐）的发射率较低。XRD分析和DFT计算表明，扭曲控制芳烃功能是获得咪唑鎓-芳烃二元体高效固态荧光的关键。
