Structurally simple pyrazole derivatives that exhibit excited-state intramolecular proton transfer (ESIPT) were synthesized. While these compounds displayed deep violet fluorescence in solution, in the crystalline state they showed white emission from the enol and keto forms.
合成了具有激发态分子内质子转移（ESIPT）的结构简单的吡唑衍生物。虽然这些化合物在溶液中呈现深紫色荧光，但在结晶状态下，它们显示出烯醇式和酮式的白色发射。
