“…In contrast with the bulk syntheses of microsized crystallites, the preparation of free-standing thin films remains a substantial synthetic challenge. Nevertheless, the preparation of thin films on various substrates has been investigated, including single-layer graphene (SLG), , highly oriented pyrolytic graphite (HOPG), ,− metal substrates Ag(111), , Au(111), ,,− and copper foil (SLG-copper), the glass substrate, , three-dimensional graphene (3DG), porous ceramic α-Al 2 O 3 substrate, amine-modified reduced graphene oxide (NH 2 – r GO), hexagonal boron nitride (hBN), polydopamine-coated capillary, 3-aminopropyl-trimethoxysilane (AMS)-functionalized silicon wafer (Si-AMS), amino-functionalized carbon nanotubes (CNTs), and diboronic-acid-attached graphene oxide (GO) . Among these substrates, SLG, HOPG, the glass substrate, hBN, metal substrates (Ag(111), Au(111)), and copper foil (SLG-copper)) have been used to prepare single-layer COFs (sCOFs) (Table ).…”

Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers with permanent porosity and highly ordered structures. Unlike other polymers, a significant feature of COFs is that they are structurally predesignable, synthetically controllable, and functionally manageable. In principle, the topological design diagram offers geometric guidance for the structural tiling of extended porous polygons, and the polycondensation reactions provide synthetic ways to construct the predesigned primary and high-order structures. Progress over the past decade in the chemistry of these two aspects undoubtedly established the base of the COF field. By virtue of the availability of organic units and the diversity of topologies and linkages, COFs have emerged as a new field of organic materials that offer a powerful molecular platform for complex structural design and tailor-made functional development. Here we target a comprehensive review of the COF field, provide a historic overview of the chemistry of the COF field, survey the advances in the topology design and synthetic reactions, illustrate the structural features and diversities, scrutinize the development and potential of various functions through elucidating structure−function correlations based on interactions with photons, electrons, holes, spins, ions, and molecules, discuss the key fundamental and challenging issues that need to be addressed, and predict the future directions from chemistry, physics, and materials perspectives.

“…For example, Fe-porphyrin-based COFs were used to decompose hydrogen peroxide, and also in the obtention of highly ordered pyrolytic graphite. [29] Nevertheless, all the examples presented above require the challenging design of ligands as building blocks that contain two, three or four functional groups in the appropriate symmetry, able to condensate into the COF structure. This requirement directly affects the final structure of the COF and usually implies difficult syntheses.…”

“…Porphyrin has a similar molecular structure, distribution of π-electron cloud, and coordination effect to corrole. Despite the porphyrin-based COFs been extensively investigated into the field of catalysis, [90][91][92] organic optical, [93,94] and biological detection, [95] it remains a challenge to build crystalline one because of the nonplanar configuration and strong electrostatic interactions. Yaghi constructed a series of porphyrin-Co based frameworks (COF-366-X-Co, X = none, OMe 2 , F, and F 4 ) with different electronegative atoms and electrophilic functional groups to regulate their the electronic structures.…”

Covalent–organic frameworks (COFs) are especially interesting and unique as their highly ordered topological structures entirely built from plentiful π‐conjugated units through covalent bonds. Arranging tailorable organic building blocks into periodically reticular skeleton bestows predictable lattices and various properties upon COFs in respect of topology diagrams, pore size, properties of channel wall interfaces, etc. Indeed, these peculiar features in terms of crystallinity, conjugation degree, and topology diagrams fundamentally decide the applications of COFs including heterogeneous catalysis, energy conversion, proton conduction, light emission, and optoelectronic devices. Additionally, this research field has attracted widespread attention and is of importance with a major breakthrough in recent year. However, this research field is running with the lack of summaries about tailorable construction of 2D COFs for targeted functionalities. This review first covers some crucial polymeric strategies of preparing COFs, containing boron ester condensation, amine‐aldehyde condensation, Knoevenagel condensation, trimerization reaction, Suzuki CC coupling reaction, and hybrid polycondensation. Subsequently, a summary is made of some representative building blocks, and then underlines how the electronic and molecular structures of building blocks can strongly influence the functional performance of COFs. Finally, conclusion and perspectives on 2D COFs for further study are proposed.
