Front Cover: Increasing the Fluorescence Quantum Yield and Lifetime of the Flavin Chromophore by Rational Design (ChemPhotoChem 7/2023)

Abstract

The Front Cover illustrates a full strike in fluorescence! Double fluorination of isoalloxazines at positions 7 and 8, to which quantum chemistry has pointed at, gives compounds with the highest fluorescence quantum yields reported so far for its class. The mallet shows the power of fluorination for the modulation of intersystem crossing when aimed delicately. The corresponding difluorinated flavins show even higher quantum yields when using deuterated solvents. Cover design by Marie Glasewald.
