“…[19,20] Porous COF materials exhibit several unique merits, principally including well-defined and foreseeable organic microporous / mesoporous architectures, good physicochemical stability, modifiable porous surface, and tailorable structures or properties. As a consequence, they exhibit great potential in practical applications for catalysis, [21,22] sensing, [23,24] separation, [25,26] and environmental governance. [27,28] Recently, porous COFs have been not only defined as splendid sorbents for a variety of gases, especially CO 2 , [29][30][31] but also applied as late-model of heterogeneous catalysts for different reactions.…”
