ESIPT-Induced photocyclization of N,N′-diphenyl-1,5-dihydroxy-9,10-anthraquinone diimine
Abstract
Photolysis of N,N′-diphenyl-1,5-dihydroxy-9,10-anthraquinone diimine affords acridine-condensed aromatic compounds via excited-state intramolecular proton-transfer, as revealed by time-resolved IR spectroscopy.
