Recently, the paper Precise Manipulation of Excited-State Intramolecular Proton Transfer via Incorporating Charge Transfer toward High-Performance Film-Based Fluorescence Sensing (J. Am. Chem. Soc., 2023, 145, 7408-7415) published in 2023 in the Journal of the American Chemical Society by Dr. Liu Ke, a Postdoctoral Fellow of the Institute of New Concept Sensors and Molecular Materials, was selected as an ESI Highly Cited Paper, with citations from journals such as JACS, Angew. Chem. Int. Ed., Adv. Sci.

This work develops a new mechanism of intramolecular charge interaction modulation of excited state proton transfer by introducing intramolecular cross-space charge interaction using excited state intramolecular proton transfer fragments as receptor structures. The fluorescent sensing film system constructed based on this work can realize the efficient detection of 2-chloroethyl sulfide gas (mustard gas simulant).

The sole author unit of the paper is Shaanxi Normal University, and the first author Dr. Ke Liu is now employed at Northwest Agriculture and Forestry University.
