本文首先合成了的β-二酮类物质作为第一配体,制备具有强荧光性质的稀土Eu配合物,无皂乳液聚合法制备了种子微球,修改的种子溶胀法制备了掺杂Eu配合物的羧基荧光聚苯乙烯微球。通过荧光分光光度计和透射电子显微镜,对其荧光性质和微球形貌进行了表征;电导率法对微球表面羧基含量进行了测量。结果表明:制备出了单分散好,表面光滑,粒径均一,约为250nm的羧基荧光微球,其表面羧基含量为1.39mmol/g。 In this paper, the first synthesis of β-diketone as the first ligand, prepared with strong fluorescence of rare earth Eu complexes, soap-free emulsion polymerization prepared seed microspheres modified seed doping prepared Eu complex Carboxyl Fluorescent Polystyrene Microspheres. The fluorescence properties and morphology of the microspheres were characterized by fluorescence spectrophotometer and transmission electron microscopy. The carboxyl content of the microspheres was measured by conductivity method. The results showed that carboxyl fluorescent microspheres with good monodispersity, smooth surface and uniform particle size of about 250 nm were prepared. The surface carboxyl groups were 1.39 mmol / g.
