Abstract

Abstract : Multistate UV to NIR electrochromism and electrofluorochromism via smart modulation of intramolecular and intervalence charge transfer transitions in dibenzophenazine-arylamine derivatives was demonstrated. Abstract : An intriguing case of intramolecular and intervalence charge transfer-driven multistate electrochromism and electrofluorochromism in dibenzophenazin-(phenyl)methanone and arylamine-based redox-active donor–acceptor–donor molecules was elucidated. Tunable absorption from UV to NIR and on–off switching of fluorescence in a single-component all-organic molecular material by a subtle variation of electric potentials were demonstrated.
