Researchers created simple pyrazole derivatives that can undergo excited-state intramolecular proton transfer (ESIPT).
In solution, these compounds emitted a deep violet fluorescence.
However, when in the crystalline state, they exhibited white light emission from both the enol and keto forms.

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.
