“…However, due to their inherent coordination bond connections, the stability of MOFs often remains limited. Moreover, most MOF-based catalysts require a cocatalyst. − To explore alternative heterogeneous catalysts, organic porous materials such as porous organic polymers (POPs) − and covalent organic frameworks (COFs) − have been extensively studied. POPs are typically composed of organic units connected by covalent bonds.…”

The cycloaddition reaction involving CO 2 and epoxides to generate cyclic carbonates represents a viable method for CO 2 utilization. However, the challenge still lies in catalyzing this reaction under solvent-free, cocatalyst-free, and mild conditions. In this study, we constructed a robust mesoporous covalent organic framework (COF) platform that features flexible quaternary ammonium groups covalently affixed inside the pore walls of these COFs. By meticulously adjusting the density of these quaternary ammonium entities, we struck a balance between the active site density and porosity of the COFs. This guaranteed access to the active sites, resulting in an effective heterogeneous catalyst. Utilizing the COF-50%QA (where QA denotes quaternary ammonium) catalyst under conditions of 100 °C and 0.1 MPa of CO 2 , the CO 2 −epoxide cycloaddition reaction demonstrated superior performance with an exceptional yield of 98% and a selectivity surpassing 99%. This work not only broadens the scope of COF-based heterogeneous catalysts for CO 2 cycloaddition reactions but also offers valuable understanding into the strategy for design and structure−property relationships of such catalysts.
