Encouragingly, piezocatalysis is proposed as an emerging and appealing strategy to drive the migration and separation of photoinduced carriers. Nevertheless, the source of piezocatalysis is usually derived from high energy-consuming ultrasonic vibration.

This paper focuses on the investigation of hydrogen bond geometric changes, the ESIPT mechanism, and its behavior modulated by solvent polarity. The structural parameters of the ground-state (S<sub>0</sub>) and excited-state (S<sub>1</sub>) related to the hydrogen bond (O<sub>1</sub><img>H<sub>2</sub>⋯O<sub>3</sub>), along with the infrared vibrational spectra, core-valence bifurcation (CVB) index, hydrogen bond bond-critical point (BCP) parameters, RDG function isosurfaces, and scatter plots, reveal that the enhanced hydrogen bond strength in the S<sub>1</sub> state promotes the ESIPT behavior of 9-10-HBQ-PT1. Further frontier molecular orbital and natural Population Analysis (NPA) charge analyses indicate that intramolecular charge redistribution facilitates the ESIPT process.

The present study reveals that both species undergo barrierless ESIPT process, and the underlying reason for fluorescence quenching in 3FTF has been elucidated.
