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.
