Photochemical afterglow of single organic molecules with wide‐range tunable lifetime

PhotoMat, EarlyView., 2023
“All‐in‐one” strategy was used to achieve photochemical afterglow in single organic molecule, with second‐to‐hour range tunable lifetime by tailoring the electron‐withdrawing ability of substituents. Abstract Background Photochemical afterglow that relies on slow release of photons from the chemical energy stored by light pre‐irradiation has emerged as
