Abstract

Our theoretical results show that the fluorescence quenching of DFAN is caused by PET mechanism and the large Stokes shift fluorescence emission of DFAH is not due to the ESIPT mechanism. Due to the absence of PET process, enol structure emits strong fluorescence, which is inconsistent with the fluorescence mechanism in the experiment.
