| 摘 要： | 采用双酚A（BA）、双酚A硫酰氟和荧光素进行高温溶液缩聚反应，制备了荧光聚硫酸酯（PSE-FL），并对其进行了结构表征及荧光特性研究。结果表明，制备的PSE-FL的数均分子量为33 413 g/mol，重均分子量为55 043 g/mol，分子量分布指数为1.64，为典型的无定形聚合物，分解温度约为319 ℃，玻璃化转变温度约为128 ℃。固体紫外吸收测试结果表明，PSE-FL在502 nm处有最大吸收波长，荧光发射光谱表明PSE-FL在554 nm处显示出荧光发射波长。

| Abstract: | Fluorescent polysulfate （PSE-FL） was prepared by condensation polymerization of bisphenol A （BA）, propane-2,2-diyl bis（4,1-phenylene） bis（sulfurofluoridate） and fluorescein in high temperature solution, and its structure and fluorescence characteristics were investigated. The results showed that the number average molecular weight of the prepared PSE-FL was 33 413 g/mol, the weight average molecular weight was 55 043 g/mol and the molecular weight distribution index was 1.64. It was a typical amorphous polymer with decomposition temperature about 319 ℃ and a glass transition temperature about 128 ℃. The solid ultraviolet absorption test results showed that PSE-FL had the maximum absorption wavelength at 502 nm and the fluorescence emission spectrum showed that PSE-FL displayed the fluorescence emission wavelength at 554 nm. |
