Reticular Synthesis of Covalent Organic Frameworks with kgd-v Topology and Trirhombic Pores.

Two-dimensional (2D) covalent organic frameworks (COFs) with designable pore structures can be synthesized under the guidance of topology diagrams. Among the five existing edge-transitive topological nets, topology is considered a fine candidate for constructing COFs with ultramicropores. However, all of the reported COFs with topology need the use of -symmetric monomers, which are limited in compound type and difficult to synthesize.
