Abstract

The Front Cover illustrates ultrafast spectroscopic insights into photoexcited energy relaxation pathways of the cationic green fluorescent protein (GFP) chromophore derivatives in aqueous solution. The electron-withdrawing and electron-donating groups (EWGs and EDGs) notably affect the ring-twisting rates on femtosecond-to-picosecond timescales, whereas excited-state proton transfer (ESPT) to solvent molecules occurs more rapidly in competition. Cover design by Jiawei Liu, Cheng Chen, and Chong Fang. More information can be found in their Research Article (DOI 10.1002/cptc.202400037).

封面：阳离子绿色荧光蛋白发色团中的取代基效应：超快激发态质子转移还是扭曲？(ChemPhotoChem 7/2024)

封面展示了对水溶液中阳离子绿色荧光蛋白（GFP）发色团衍生物光激发能量弛豫途径的超快光谱研究。在飞秒到皮秒的时间尺度上，电子吸取基团和电子捐献基团（EWGs 和 EDGs）对环扭转速率有显著影响，而激发态质子向溶剂分子的转移（ESPT）在竞争中发生得更快。封面设计：刘嘉伟、陈诚、方重。更多信息请参阅他们的研究文章（DOI 10.1002/cptc.202400037）。
