Two new ionic porous organic polymers (iPOPs) with different counter anions were successfully fabricated via well-known pyrylium mediated transformation into pyridinium. ¹³C solid-state NMR, XPS, and FTIR were analyzed and confirmed the formation of pyridinium in the network. Containing charged and aromatic networks, both iPOPs exhibit a high affinity towards toxic hexavalent chromium Cr(VI) ions. What is more, it has been demonstrated that both CO₂ adsorption and Cr(VI) removal properties can be tuned by simply varying counter anions.

P介导的转化构建离子多孔有机聚合物（iPOPs）

通过众所周知的吡啶介导的向吡啶鎓的转化，成功地制备了两种具有不同抗衡阴离子的新型离子多孔有机聚合物（iPOPs）。^分析了13 C固态NMR，XPS和FTIR，并确认了网络中吡啶鎓的形成。包含带电和芳香族网络，这两个iPOPs对有毒的六价铬Cr（VI）离子都具有很高的亲和力。而且，已经证明可以通过简单地改变抗衡阴离子来调节CO ₂吸附和Cr（VI）去除性能。
