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 کاملCatalytic covalent organic frameworks via pore surface engineering.
We report a synthetic strategy for construction of the first example of organocatalytic covalent organic frameworks via pore surface engineering. The COF catalyst combines a number of striking features, including enhanced activity, broad applicability, good recyclability, and high capability, to perform catalytic transformation under continuous flow conditions.
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 کاملBifunctional covalent organic frameworks with two dimensional organocatalytic micropores.
We report the successful incorporation of bifunctional (acid/base) catalytic sites in the crystalline organocatalytic porous COF (2,3-DhaTph). Due to the presence of acidic (catachol) and basic (porphyrin) sites, 2,3-DhaTph shows significant selectivity, reusability, and excellent ability to perform the cascade reaction.
