Front Cover: Substituent Effects in the Cationic Green Fluorescent Protein Chromophore: Ultrafast Excited-State Proton Transfer or Twisting? (ChemPhotoChem 7/2024)
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).
