Reticular synthesis of microporous and mesoporous 2D covalent organic frameworks.
Reticular chemistry is concerned with linking molecular building blocks into predetermined periodic structures using strong bonds.1 This chemistry has led to the design and synthesis of new porous materials for which the composition, structure, metrics, and functionality can be systematically varied.2,3 The general nature of this approach is epitomized by the recent reports of covalent organic ...
متن کاملColloidal Covalent Organic Frameworks
Covalent organic frameworks (COFs) are two- or three-dimensional (2D or 3D) polymer networks with designed topology and chemical functionality, permanent porosity, and high surface areas. These features are potentially useful for a broad range of applications, including catalysis, optoelectronics, and energy storage devices. But current COF syntheses offer poor control over the material's morph...
متن کاملChemistry of Covalent Organic Frameworks.
Linking organic molecules by covalent bonds into extended solids typically generates amorphous, disordered materials. The ability to develop strategies for obtaining crystals of such solids is of interest because it opens the way for precise control of the geometry and functionality of the extended structure, and the stereochemical orientation of its constituents. Covalent organic frameworks (C...
متن کاملDesigned synthesis of double-stage two-dimensional covalent organic frameworks
Covalent organic frameworks (COFs) are an emerging class of crystalline porous polymers in which organic building blocks are covalently and topologically linked to form extended crystalline polygon structures, constituting a new platform for designing π-electronic porous materials. However, COFs are currently synthesised by a few chemical reactions, limiting the access to and exploration of new...
متن کاملSynthesis of chemically stable covalent organic frameworks in water
The development of environmentally benign and scalable synthetic routes to chemically stable covalent organic frameworks (COFs) is key to their real world application in areas such as gas storage and proton conduction. Banerjee et al. [IUCrJ (2016), 3, 402-407] have exploited the high chemical stability of the keto-enamine linkage to develop a 'green' water-mediated procedure, presenting a scal...
