THE DIFFERENT RECOGNITION MECHANISM OF CARBAZOLE DERIVATIVES FOR BIOLOGICAL IMPORTANT ANION: THEORY AND EXPERIMENT

Two fluorescent anion sensors bearing phenol, carbazole-NH and -NO2 group were designed and synthesized. They both exhibited highly binding ability for H2PO4- among the anions tested. In the presence of H2PO4-, the fluorescence of the sensors underwent a dramatic enhancement, while the presence of o...
