Reticular chemistry in action: 3D porphyrinic COFs with scu topology

Rational design, synthesis, and structural determination of 3D covalent organic frameworks (COFs) with novel topologies remain a formidable challenge. In this issue of Chem, Zhang and co-workers develop an intriguing strategy for constructing highly crystalline and non-interpenetrated 3D porphyrinic COFs with scu topology and possessing some excellent photocatalytic efficiencies.

Rationally fabricating 3D porphyrinic covalent organic frameworks with scu topology as highly efficient photocatalystsJin et al.ChemAugust 19, 2022In BriefUsing a rare 8-connected building block, two porphyrin-based three-dimensional covalent organic frameworks (3D COFs) were rationally designed and synthesized through an [8 + 4] construction approach. Upon the assistance of the continuous rotation electron diffraction (cRED) technique, the COF structures were precisely determined to be 3D open networks with scu topology, which had not been achieved in the COF field. Attributed to the enriched porphyrin catalytic sites, these COFs exhibited excellent photocatalytic activity and cyclic stability. Full-Text PDF
