ABSTRACT
Triphenylimidazole-based ampholytes with intramolecular charge transfer were designed with the introduction of carboxyl groups. In solution, the synergistic solvent and ionization effects on the ampholytes led to a unique pendulum-type fluorescence variation during the water content increasing process. Among them, 4-(4,5-bis(4-hydroxyphenyl)-1H-imidazol-2-yl)benzoic acid showed the most prominent three-step fluorescence switching property.
