Abstract: In order to prepare high-performance bonded polymer-rare earth complex luminescent materials and explore the relationship between their structure and luminescent properties,functionalized polysulfone (PSF-NGly) containing naphthalene formaldehyde condensation glycine Schiff base ligand structure was prepared through three steps of macromolecular reactions. The products of each step were characterized byinfrared,proton nuclear magnetic resonance,ultravioletand ninhydrin colorimetric methods. The obtained PSF-NGly was coordinated with rare earth Eu(II) ions to form the polymer-rare earth complex PSF-(NGly) -Eu(II). The luminescent properties of PSF-(NGly) -Eu( Il )were de3 3 termined by fluorescence spectroscopy. The results showed that the naphthalene formaldehyde condensation glycine Schiff base group was successfully bonded to the polysulfone side chain,and the macromolecular ligand PSF-NGly produced an “Antenna” effect on the Eu(II) ion.The complex PSF- (NGly)3 1 Eu(II) had excellent luminescent properties.
