A novel heteroacene 2-(perfluorophenyl)-1H-imidazo[4,5-b]phenazine for selective sensing of picric acid†
Abstract
A novel sensing probe, 2-(perfluorophenyl)-1H-imidazo[4,5-b]phenazine (PFIPZ) containing imidazole and phenazine units, has been successfully synthesized and can identify picric acid over other electron-deficient compounds or strong acids.
