新型蓝色荧光聚合物纳米粒子的合成与表征

Synthesis and Characterization of Novel Blue Fluorescent Polymer Nanoparticles

采用细乳液聚合法将可聚合的蓝色荧光单体4-乙氧基-9-(2-烯丙基)-1,8-萘二甲酰亚胺(EANI)与甲基丙烯酸甲酯(MMA)进行共聚,通过改变聚合物纳米粒子中EANI的含量,制得了不同荧光强度的新型蓝色荧光聚合物纳米粒子。通过光谱学研究表明,EANI是通过共价键的方式与聚合物纳米粒子相结合。

A novel blue fluorescent polymer nanoparticles was prepared by the miniemulsion copolymerization of a blue fluorescent dye monomer 4-ethoxyl-9-allyl-1,8-naphthalimide（EANI） and methyl methacrylate（MMA）.The fluorescent polymer nanoparticles with different fluorescence intensity could be obtained by control the content of the EANI dye.Spectroscopic characteristics demonstrate that EANI was successfully covalently incorporated into the polymeric nanoparticles.
