Porous ionic polymers (PiPs) are newly emerging organic porous polymers. In sharp contrast to charge-neutral porous polymers, ionic moieties are either incorporated into the polymer backbone, or are covalently attached to a polymeric framework. Therefore, their physicochemical properties, functional groups, and active sites can be easily modified through screening of building blocks and ionic tectons. Meanwhile, their surface area, pore size, and pore volume can also be tuned by counterions exchange. Intrinsic functionalization further broadens the application range of the PiPs. This review will describe the recent advancements with regard to PiPs, and their development in the area of gas adsorption, catalysis, antibacterial applications and water purification.

多孔离子聚合物（PiPs）是新兴的有机多孔聚合物。与电荷中性的多孔聚合物形成鲜明对比的是，离子部分或者被掺入到聚合物主链中，或者被共价附接到聚合物骨架上。因此，它们的物理化学性质，官能团和活性位点可通过筛选结构单元和离子构造容易地进行修饰。同时，它们的表面积，孔径和孔体积也可以通过抗衡离子交换来调节。内部功能化进一步扩大了PiP的应用范围。这篇综述将描述PiPs的最新进展及其在气体吸附，催化，抗菌应用和水净化领域的发展。
