The development of three-dimensional (3D) functionalized covalent–organic frameworks (COFs) is critical importance for expanding their potential applications. However, the introduction functional groups in 3D COFs remains largely unexplored. Herein, we report first example Salphen-based (3D-Salphen-COFs) and metal-containing counterparts (3D-M-Salphen-COFs). These exhibit high crystallinity specific surface area addition to excellent chemical stability. Furthermore, Cu(II)-Salphen COF...

To better understand the structure–catalytic property relationship, a platform of urea-containing MOFs with diverse topologies as hydrogen-bonding (H-bond) catalyst has been well established in present work. During construction MOFs, we proposed new strategy called isoreticular functionalization approach which desired topological net is first considered blueprint, and then two predesigned functionalized polydentate ligands link to four different metal clusters by de novo routes achieve...

Molecular engineering of covalent organic frameworks (COFs) offers an alternative approach to conventional anthraquinone oxidation via photo‐induced H2O2 production from O2 reduction. Despite their potential, reported photocatalysts suffer limited proton mobility, low selectivity, and insufficient charge separation utilization. Herein, we report a nitroxyl radical (TEMPO) decorated two‐dimensional (2D) donor‐acceptor (D‐A)‐COF photocatalyst one‐pot strategy linking the porphyrin unit. Under...

A three-dimensional metal-covalent organic framework (3D-MCOF) based on cyclic trinuclear units was synthesized using tetrahedral linkers and copper-based complexes. The novel type of 3D-MCOF, named 3D-CTU-MCOF, with the ctn topology, is reported herein for first time. Our study demonstrated enhanced electrocatalytic capacity CO2 reduction reaction 3D-CTU-MCOF compared to independent units.
