THE FLUORESCENCE QUENCHING OF ACRIDINE CONTAINING TER-CO-POLYMER MEMBRANE BY HALIDES

doi:10.7517/j.issn.1674-0475.2003.01.53

Abstract

Abstract: Based on the synthesis of different terpolymers with acridine group,the absorption and fluorescence spectra of these compounds in solution and membrane were recorded respectively.The fluorescence quenching of membrane of these copolymers by different halides was also studied in this work.It was found that the copolymer with different ratio of composition of acridine contained possesses different selectivity for halides.The unsuitable containing of acridine in copolymers will reduce the ability for the molecular recognition of halides.The good results have been obtained just for the membranes in which certain composition of acridine was contained.A detailed discussion was also included.

Key words: acridine containing terpolymer, halogen anions, molecular recognition, fluorescence quenching
