Abstract

A novel compound,2-(2,4-dibromophenol)-1H-imidazo[4,5-f][1,10] phenanthroline(4),was synthesized by condensation of 3,5-dibromo-salicyaldehydel with 1,10-phenanthroline-5,6-diamine which was prepared from 1,10-phenanthroline by a three-step reaction.The structure of 4 was characterized by 1H NMR,IR,elements analysis and X-ray crystal diffraction analysis.The recongnition properties of 4 with six anions(X-= F-,Cl-,Br-,I-,H2PO2-4,AcO-) were investigated in DMSO by UV-Vis and fluorescence.The results showed that 4 exhibited selectively recognized propertied for AcO-,F-and H2PO2-4.
