Porous organic frameworks(POFs)have emerged as a new family of porous materials in the field of gas storage and separation,sensors,and catalysis[1].For constructing POFs,it should select suitable building blocks and effective reaction.More than thirty porous aromatic framework(PAF)materials have been successfully designed and synthesized.The introduction of functional groups into PAF skeletons is achieved thanks to the flexibility of building blocks[2,3].Subsequently,their corresponding post-modified products are obtained,and the property of pore surface functionality could be tuned.
