Construction of Ionic Porous Organic Polymers (iPOPs) via Pyrylium Mediated Transformation

Two new ionic porous organic polymers (iPOPs) with different counter anions were successfully fabricated via well-known pyrylium mediated transformation into pyridinium. 13 C solid-state NMR, XPS, and FTIR were analyzed and confirmed the formation of pyridinium in the network. Containing charged and...

Zusammenfassung:	Two new ionic porous organic polymers (iPOPs) with different counter anions were successfully fabricated via well-known pyrylium mediated transformation into pyridinium. 13 C 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 CO 2 adsorption and Cr(VI) removal properties can be tuned by simply varying counter anions.
