通过双吡啶鎓盐的转化设计并合成了主链上带正电荷的聚吡啶鎓盐（PPS）。此类材料表现出良好的从水中捕获铼的吸收能力，以及对竞争阴离子的 ReO4- 的优异选择性。此外，易于合成和大规模制备的优点使得该材料具有在工业上实际应用的前景。
Poly(pyridinium salts) (PPSs) with positive charges on the backbones were designed and synthesized from the transformation of bispyrylium salts. Such materials exhibited good uptake capacity for rhenium capture from water, and excellent selectivity of ReO4- from competing anions. Furthermore, the advantages of facile synthesis and large-scale preparation make this material promising for practical use in industry.
