Abstract

Abstract:

Polymeric fluorescent chemosensor, poly(NIPAM_m-co-Nap_n) (abbreviation as PNap334), has been synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. The copolymer consists of 1,8-naphthalimide as luminophore and benzamide as fluoride ions (F^-) selective detection unit. The F^-responsive properties of the resulted copolymer PNap334 were investigated in DCM/DMSO (9/1, V/V) solution and film, respectively. Based on an intermolecular proton transfer (IPT) and induced intramolecular charge transfer (ICT) mechanism, the polymeric chemosensor displays distinct selective detection of F^- both in solution and film. And the detection limit of F^- in solution is 1.05 μmol/L.

Key words: RAFT, copolymer, probe, fluoride anions
