A novel electropolymerized fluorescent film probe for TNT based on electro-active conjugated copolymer.

ABSTRACT

A novel electro-active conjugated copolymer (PFPCz) has been designed, synthesized and used as the precursor of electropolymerization (EP) directly. By optimizing the EP condition, the PFPCz EP films have been prepared and displayed high fluorescent sensitivity to TNT, whose fluorescent intensity could be quenched 68.6% exposed to TNT (50 µM) in aqueous medium. These results suggest PFPCz EP film a promising candidate for TNT detection. Furthermore, this work provides not only a new precursor to EP but also a promising fluorescence film sensor candidate.
