AbstractCovalent organic frameworks (COFs) with highly ordered crystalline structures and uniform microenvironments have potential applications in the field of catalysis; however, their application is restricted by their harsh synthesis conditions and multi-step synthetic procedures. Herein, we report the facile synthesis of a new COF-salen via in situ salen skeleton formation by heating aldehyde and amine precursors in an air atmosphere. This COF-salen possesses an AA stacking eclipsed layered crystalline structure, micro/macro hierarchical pores, and high stability in acid or base medium and can be efficiently transformed to COF-salen-M (M = Co, Mn, Cu, Zn) with a well-retained ordered crystalline structure. The successful application of COF-salen-Co(iii) and COF-salen-Mn, respectively, in epoxide hydration, which requires the cooperation of two salen-Co(iii), and olefin epoxidation, in which the isolated salen-Mn functions as the active site, can be attributed to their unique layered crystalline structures; these structures can efficiently isolate the active sites by restricting their mobility and generate cooperation between nearby active sites in adjacent layers. COF-salen-Co exhibited much higher activity and stability than the corresponding amorphous polymers in cycloaddition reactions of epoxides with CO2, demonstrating the advantage of the crystalline structure in catalysis.
