Zn(II) based mixed complex with 8-hydroxyquinoline end group functionalized PSt and the study of fluorescent properties

Abstract Functionalized polystyrene containing 8-hydroxyquinoline end group (PSt-CH 2 -Q) was prepared through atom transfer radical polymerization (ATRP). The functionalized polystyrene and organic ligands were used to prepare mixed complex of Zn(II). The structure of the complexes was characterized through 1 H NMR, FTIR and fluorescent spectra. When excited at 336 nm, zinc (PSt-CH 2 -Q) o -aminobenzoic acid complex emitted strong blue light at 404 nm. Zinc (PSt-CH 2 -Q) phenanthroline complex emitted at 410 nm. The Emission of zinc (PSt-CH 2 -Q) o -aminobenzoic acid was stronger than that of zinc (PSt-CH 2 -Q) phenanthroline by one order of magnitude.
