A series of novel nitrogen- and sulfur-containing conjugated polymers with well-defined conjugation length have been synthesized via an acid-induced self-polycondensation of functional monomers with methylsulfinyl groups. Synthesized polymers exhibit good solubility in common solvents, such as CHCl3, THF, DMF, DMSO, and NMP. With increased numbers of aminophenyl groups, these polymers have shown similar electrical properties to polyaniline (PAn), and these are demonstrated by UV–vis spectroscopy and cyclic voltammetry (CV) measurements on the polymers. The conductivity of preliminarily protonic-doped poly[phenylene sulfide-alt-tetrakis(aniline)] (PPSTEA) is up to 10−1 S cm−1.
通过功能单体与甲基亚磺酰基的酸诱导自缩聚反应,合成了一系列具有明确共轭长度的新型含氮和硫共轭聚合物。合成的聚合物在常见溶剂中表现出良好的溶解度,例如CHCl3、THF、DMF、DMSO和NMP。随着氨基苯基数量的增加,这些聚合物表现出与聚苯胺 (PAn) 相似的电性能,这些性能通过聚合物的紫外可见光谱和循环伏安法 (CV) 测量得到了证明。初步质子掺杂的聚[苯硫醚-alt-四(苯胺)] (PPSTEA) 的电导率高达 10−1 S cm−1。
