A new acid base fluorescent switch containing both imidazo[4,541[1,10]-phenanthroline and triphenylamine groups has been synthesized. Its fluorescence emissions and absorptions can be reversibly changed through protonation/deprotonation of imidazole and amine moiety by controlling the intramolecular charge transfer (ICT) process, leading to off on off fluorescent molecular switching.
