8-Hydroxyquinoline lithium (Liq)-containing copelymers were synthesized by free radical copolymerization of methyl methacrylate (MMA) and a Liq-pendant monomer prepared by LiOH and 5-(2- methacryloylethyloxymethyl)-8-quinalinol.The structure of the monomer
Li(C9H5NO)CH2OCH2OOCC(CH3)- CH2·H2O
was charactefized and confirmed by 1H-NMR
TGA and elemental analysis.Compared to PMMA
the copolymer was more thermally stable.The copelymers with Liq-content<15 wt% can he dissolved well in common solvents.Ultraviolet-visible absorption.PL spectra proved that the luminescent centers mostly came from the Liq units.The monomer and the copelymer were blue-emitting matefials.It was found that the solvents.such as DMF.DMSO
which affected the conjugated electrons in quinolinolate groups can he used to modify the color of the lumineseence of the copolymer cast films.
