Fluorescent properties of 3HNA-doped PMMA composites

摘要：

　　The composites of poly(methyl methacrylate) (PMMA) and 2-hydroxy-3-naphthoic acid (3HNA) were prepared by in situ polymerization.The effect of polar solvent N,N-dimethylacetamide (DMAc) on the fluorescent properties of the composites was investigated by fluorescence spectrum.The results indicate that the composites exhibits dual emissions,which are corresponding to the normal or large Stokes-shifted fluorescence of 3HNA and the excited state intramolecular proton transfer (ESIPT),respectively.The intensity of Stokes-shifted emission changes regularly with the concentration of 3HNA-doped PMMA in DMAc.
