At present, applications of covalent organic frameworks (COFs), a class of novel crystalline porous materials fabricated by organic structural blocks only containing light elements such as C, H, N, O and B through strong covalent bonds, in electrochemical sensing have entered a period of rapid development and showed great potential in various analytical fields such as environmental analysis, food analysis, pharmaceutical analysis, biological and clinical analysis owing to their unique advantages including regular porosity, large specific surface area, periodical ordered structure, extended π‐conjugated system, abundant functional groups and outstanding thermal and chemical stability. But there are still many concerns that need to be urgently solved for further electrochemical sensing application including improvement of electric conductivity and enhancement of selectivity. Limited by poor conductivity and low recognition ability of primitive COFs, they always need to be further functionalized. To further promote the development of COFs‐based electrochemical sensing technology, here, we summarize and review the recent advances on construction of two‐dimensional functional COFs materials for electrochemical sensing applications and related sensing device setups in detail, including design strategies, preparation methods, modification considerations, sensing principles and analytical applications, and tentatively propose development prospects and outlooks in future.

“…The outstanding physical, electrical, chemical, and optical properties of C 60 fullerene make them promising candidates for use in science, engineering, and industries. [7][8][9][10] Graphene, a single sheet of graphite, is another allotrope of carbon comprising a single layer of atoms arranged in a hexagonal lattice. [11] This 2D material is also a polymer of carbon atoms, where, despite C 60 fullerene, its polymerization results in a geometrically infinite nanostructure.…”

Based on the molecular dynamics (MD) simulations, mechanical properties of the most recently synthesized covalent fullerene network, i.e., graphullerene sheet under uniaxial tension are determined. These properties include Young’s modulus, ultimate stress, failure strain, tensile toughness and Poisson’s ratio. Due to the lack of existing data on mechanical properties of graphullerene, a comprehensive study is performed to get an insight into the effects of defect density, size and temperature on all tensile characteristics. The results indicate that the tensile behavior of graphullerene structure is comparable with graphene allotropes. Moreover, it is observed that the presence of defect reduces stiffness, ultimate stress and tensile toughness, while it has a negligible effect on the failure strain. It is further observed that unlike stiffness, increasing the temperature reduces other tensile characteristics. Interestingly, it is found that graphullerene exhibits auxetic behavior with negative Poisson’s ratio which categorizes it as a unique auxetic material ever synthesized. At the end, three types of potential functions for hydrocarbons including AIREBO, REBO and Tersoff are considered to study the tensile behavior of graphullerene. This new auxetic nanosheet would be a promising analogous to existing 2D nanostructures with fascinating potential applications.This article is protected by copyright. All rights reserved.

“…Covalent organic frameworks (COFs), as a new family of porous materials, have attracted a lot of attention in recent years. [31][32][33][34][35][36][37] COFs are designed and constructed via chemical bonds between different organic monomers, so they have good crystallinity, high surface area, large pores, excellent stability, and atomic-level controllability, resulting in their potential applications in gas sorption, 38,39 sensing, 40,41 and heterogeneous catalysis. [42][43][44] Excitingly, the large pores and stable skeleton of COFs can provide an ideal platform to immobilize enzymes.…”
