Hierarchical porous poly(ionic liquid)s (PILs) with high specific surface area were firstly synthesized via anion exchange. The exchange of bulky salicylate and its dimers/clusters in PILs by other smaller anions increased the specific surface area and fabricated a hierarchical porous structure. The high specific surface area and hierarchical porous structure prompted a high degree of exposure of the active sites and made the heterogeneous PIL catalysts contact with substrates sufficiently, enhancing their catalytic activity.
首先通过阴离子交换合成了具有高比表面积的分级多孔聚离子液体（PILs）。用其他较小的阴离子交换PILs中体积较大的水杨酸酯及其二聚体/簇，增加了比表面积并构建了分级多孔结构。高比表面积和分级多孔结构促使活性位点高度暴露，并使多相PIL催化剂与底物充分接触，提高了它们的催化活性。
