Electrosynthesis of Pyrene Sulfonic Acid Oligomer and Its Application in Fluorescent Sensor

芘及其衍生物由于具有优异的荧光性能而受到研究者的极大关注。本文主要研究了稠环芳香化合物1-芘磺酸钠的化学方法合成及电化学方法聚合,并对获得的聚合物(聚1-芘磺酸钠)进行了详细的结构表征和性能测试。结果表明:聚(1-芘磺酸钠)材料是一种良好的蓝色发光材料(最大发射波长为465 nm),荧光量子产率达0.39,且在溶剂中展现出明亮的蓝色光致发光现象,其良好的荧光性能能够实现对金属离子Fe3+的选择性检测。

Pyrene and its derivatives are of great interest to researchers because of their excellent. 1-pyrenesulfonic acid sodium was successfully synthesized and its corresponding oligomer films was prepared by direct anodic oxidation of its monomer 1-pyrenesulfonic acid sodium in BFEE（0.1 mol L-1） for the first time. The UV-visible spectra of soluble oligo（1-pyrenesulfonic acid sodium） demonstrated that the higher conjugation-length oligomer/polymer was eventually formed.Soluble oligo（1-pyrenesulfonic acid sodium） is proved to be a favourable blue-emitting material, and the fluorescence quantum yields of oligo（1-pyrenesulfonic acid sodium） films was calculated to be 0.39. According to the experiment of electroluminescent performance, oligo（1-pyrenesulfonic acid sodium） was also employed as fluorescent chemosensor to sense metal ions in aqueous solution.
