Dual functionalization of porous aromatic frameworks (PAFs) has been illustrated in the context of incorporating two antagonistic sites of strong acid and strong base into the highly porous and highly robust PAF-1 via stepwise post-synthetic modification. The resulting bifunctionalized PAF-1 exhibits excellent performances in catalyzing a series of cascade reactions and demonstrates superior chemical stability compared to the counterparts of mesoporous silica and MOFs, thereby opening the door for dual functionalization of PAFs as a new platform for heterogeneous cascade catalysis.
通过逐步后合成修饰，将强酸和强碱这两个拮抗位点引入到高度多孔且高度稳定的PAF-1中，以此阐述了多孔芳香骨架（PAFs）的双功能化。所得的双功能化PAF-1在催化一系列串联反应中表现出优异的性能，并且与介孔二氧化硅和金属有机框架（MOFs）的对应物相比，具有更高的化学稳定性，从而为PAFs作为多相串联催化的新平台的双功能化打开了大门。
