摘　　要：以3,6-二氧杂-1,8-辛烷二硫醇(EGDT)和己二酸二丙烯酯(DAA)为单体,苝四羧酸丙烯酯为荧光染料,采用"巯基-双键"光聚合法制备了粒径均一、水稳定性的苝荧光纳米颗粒。通过扫描电子显微镜、红外光谱仪、荧光光谱仪和紫外-可见分光光度计等手段对其进行表征。结果表明:所制备的荧光纳米颗粒具有良好的单分散性且荧光性能好。Water stable perylene fluorescent nanoparticles with uniform particle size were synthesized by photopolymerization using 3,4,9,10-perylenetetracarboxylicacid allyl ester as fluorescent dye,dithiol（EGDT）and diallyl（DAA）as the monomer.These fluorescent nanoparticles were characterized by scanning electron microscopy,fourier transform infrared measurement,fluorescence microscopy,UV-Vis spectrophotometer and so on.The results indicated that fluorescent nanoparticles with good dispersion and high fluorescence intensity were obtained.
