Proton Transfer Process

The proton transfer reaction in methyl 5-R-salicylate is found to be highly sensitive to the presence of specific substituents in resonance with the hydroxyl group, leading to different fluorescence behaviors of methyl 5-R-salicylate with different substituents.

Intramolecular Proton Transfer

When excited with high energy quanta, specially designed 3-hydroxychromone derivatives demonstrate dramatic enhancement of the excited-state intramolecular proton transfer (ESIPT) reaction in obvious violation of Kasha's rule.
