Excited-state dynamics of 4-hydroxyisoindoline-1,3-dione and its derivative as fluorescent probes
Zhao Li, Simin Jiang, Yan‐Mei He, Luling Wu, Tony D. James, Junsheng Chen
Abstract
an efficient nonradiative process (∼300 ps) due to the presence of a minimum energy conical intersection between its first excited state and ground state. However, upon reacting with peroxynitrite, the Bpin moiety is cleaved from BHID-Bpin and BHID is formed. The formed BHID exhibits strong dual band fluorescence which is caused by an ultrafast excited-state intramolecular proton transfer process (∼1 ps).
