Synthesis, characterization and fluorescent performance studies of novel diphenyl sulfone-functionalized water-soluble polymer

Abstract

In this communication, a novel water-soluble diphenyl sulfone-functionalized polymer was successfully synthesized through a facile hydrothermal synthesis route and then characterized by FT-IR, UV?Vis, 1H-NMR and 13C- -NMR spectroscopy. Fluorescence quenching experiments revealed that the fluorescence intensities of the resulting diphenyl sulfone-functionalized polymers were linear with the concentrations of Fe3+ and 4-nitrophenol (4-NP) in the concentration ranges of (5.0?24.9)?10-8 and (5.0?50.0)?10-7 mol dm-3, with detection limits of 2.8?10-8 and 2.2?10-7 mol dm-3, respectively. These results created opportunities for the development of novel chemosensors by introducing selective fluorescent groups into polymeric materials.
