| Abstract: | A new acid-base fluorescent switch containing both imidazo4,5-f]1,10]-phenanthroline and triphenylamine groups has been synthesized.Its fluorescence emissions and absorptions can be reversibiy 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. |
| Keywords: | Fluorescence switch Imidazo[4 5-f][1 10]phenanthroline Triphenylamine Intramolecular charge transfer(ICT) |
