重要传感材料荧光共轭聚合物PPESO3的一种新的简便合成路线

本文提出了一种新的简便得多的合成路线, 既避免了BBr3的使用, 又简化了反应步骤, 使PPESO3的合成简单易行, 为更广泛地对其进行研究与应用提供了便利条件. 此外, 本文还研究了PPESO3与非离子表面活性剂(聚乙烯吡咯烷酮, PVP)之间的相互作用, 结果表明, PVP与PPESO3形成了稳定的络合体, 可以有效地打破聚合物在水溶液中的聚集, 提高荧光量子产率.

A Facile Synthetic Route for an Important Sensing Material Fluorescent Conjugated Polymer PPESO3

A facile synthetic route for conjugated polymer PPESO_(3) was proposed,through which not only the procedure was simplified,but also the dealkylation by BBr_(3) was avoided,and therefore,the preparing difficulty and danger were greatly reduced,which was obviously beneficial to the preparation and application of(PPESO_(3)).At the same time,the interactions between(PPESO_(3)) and nonionic surfactant(PVP) were investigated.The results indicate that the aggregation of polymer backbone was effectively broken up and the steady complexes consisted of PPESO_(3) and PVP were formed which would contribute to the preparation of highly sensitive bio-sensors due to the affinity of PVP to biological macromolecules.
