Synthesis of Polyarylene sulfonium as a Novel Polymer and Its Properties based on the Hyper-polarizedpi-Conjugate Structure

以对苯硫基苯基三氟甲磺酸为原料，通过亚砜-酸反应合成了聚对苯硫基苯基三氟甲磺酸S。研究了所得聚磺盐的亲核反应，以阐明其化学反应活性。硫酸盐与亲核试剂如卤素离子的脱烷基反应可以有效地生成聚芳硫醚，这也与相应单体硫酸盐的控制反应进行了比较。UV-Vis光谱的动力学分析表明，脱烷基反应定量地从硫醚键转化为硫醚键。卤化物离子脱烷基反应的反应速率常数为I&gt；bR&gt；CL。我们建立了直接合成聚硫离子的方法。苯允许在三氟甲烷磺酸中与甲烷亚硫酸钠反应。首先，通过简单的一步合成法合成了硫基连接的亚苯基聚合物。我们还发现，许多硫化合物是通过硫化物和醚的超酸反应合成的，这是一种直接合成硫化物的方法。我们正在研究新的硫化合物的性质。

Poly[ary] or alkyl 4-(phenylthio)phenylsulfonium trifluoromethanesulfonate]s were synthesized by a sulfoxide-acid reaction from the corresponding arylsulfoxides. The nucleophilic reaction of the resulting poly(sulfonium) salts were investigated in order to elucidate the chemical reactivity. The dealkylation of the sulfonium salts with a nucleophile such as halide ions takes place effectively to yield poly(arylene sulfide), which is also compared to the controlled reaction of the corresponding monomeric sulfonium salts. Kinetic analysis by means of UV-vis spectroscopy reveals that the dealkylation proceeds quantitatively to convert to the thioether bond from the sulfonium one. The reaction rate constants of the dealkylation by the halide ions are in the order of I > Br > CLWe developed the direct synthesis of polysulfonium ion. Benzene allows to react with sodium methanesulfinate in trifluoromethane sulfonic acid. First phenylene polymers linked by sulfonium group were obtained by the simple and one-post synthesis. We also found that many sulfonium compounds were synthesized by the superacidified reaction of sulfides and ethers as a direct synthesis of sulfonium derivatives. The properties of novel sulfonium compounds are investigated in progress.
