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

Functionalized polystyrene containing 8-hydroxyquinoline end group (PSt-CH2-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 1H NMR, FTIR and fluorescent spectra. When excited at 336 nm, zinc (PSt-CH2-Q) o-aminobenzoic acid complex emitted strong blue light at 404 nm. Zinc (PSt-CH2-Q) phenanthroline complex emitted at 410 nm. The Emission of zinc (PSt-CH2-Q) o-aminobenzoic acid was stronger than that of zinc (PSt-CH2-Q) phenanthroline by one order of magnitude.
