Abstract

Abstract: Covalent organic frameworks (COFs), an emerging class of organic crystalline polymers with highly oriented structures and permanent porosity, can adopt 2D or 3D architectures depending on the different topological diagrams of the monomers. Notably, 2D COFs have particularly gained much attention due to the extraordinary merits of their extended in‐plane π‐conjugation and topologically ordered columnar π‐arrays. These properties together with high crystallinity, large surface area, and tunable porosity distinguish 2D COFs as an ideal candidate for the fabrication of functional materials. Herein, this review surveys the recent research advances in 2D COFs with special emphasis on the preparation of 2D COF powders, single crystals, and thin films, as well as their advanced optical, electrical, and magnetic functionalities. Some challenging issues and potential research outlook for 2D COFs are also provided for promoting their development in terms of structure, synthesis, and functionalities. Abstract : Recent advances in the synthesis of 2D COF powders, single crystals, and thin films, as well as their advanced optical, electrical, and magnetic functionalities are systematically summarized. The challenging issues and potential opportunities are also proposed for further inspiring their development in structure, synthesis, and functionalities.
