Abstract: The isomerization of covalent organic frameworks(COFs) materials is still a mysterious and attractive topic. Diversified monomer structures are still urgently needed to explore the in-depth mechanism of isomerization in these special COFs. This work provides a new D2h monomer for the construction of [D2h+C2] 2D COFs isomers. A new D2h monomer adopted here was proven to tend to form a single pore framework structure.

Key words: Covalent organic framework, Isomerization, Kagome, Dynamic covalent bond
