【Abstract】 In the last two decades, the research of the anion recognition has bloomed splendidly. The strong influence of the anion in the field of biological system, industry and every day life made the qualitative and quantitative research in anion recognition more and more important. After realizing the important role played by anions in biology and environment, various anions recognition hosts were synthesized. Herein, we report the synthesis of a quinoxaline based compound, namely 2,3-bis(2-pyrrole amide)methylquinoxaline(2) through seven steps reaction. The crystal structure of compound 2 was studied. The fluoride recognition propriety of compound 2 was studied by monitoring the perturbation of the UV-Vis and the fluorescent spectra of the host upon the addition of anion. The result show that compound 2 can recognize fluoride in DMSO efficiently, and the main recognition sites are pyrrole NHs and amide NHs.更多还原
