New synthetic strategies toward covalent organic frameworks

Abstract

This tutorial review highlights the representative advances in the new synthetic strategies toward covalent organic frameworks.

In silico design of 2D polymers containing truxene-based platforms: insights into their structural and electronic properties

“…Achieving crystalline order in COFs relies on the reversibility of the chemical reactions used to connect the constituting molecular units via an error-correction mechanism. 8 Among the small number of chemical reactions that are sufficiently dynamic to enable the synthesis of COFs, Schiff base (imine) formation is the only chemical transformation that gives rise to p-conjugated structures. 9 However, imine linkages are far from ideal to induce efficient p-delocalization between connected units owing to their high polarization.…”

Atoms and the void: modular construction of ordered porous solids

“…2 and 4-8, reveals that the carbon-based modules from which they are built are often complex molecules synthesized by multistep routes. An urgent goal is to learn how to make other exceptional ordered materials by simpler methods of synthesis, ideally using only inexpensive modular components that are derived from renewable resources by green methods [77][78][79][80][81][82] . Together, these challenges and opportunities ensure that modular construction will continue to be a highly dynamic area of science and technology.…”

Enzyme Immobilization in Covalent Organic Frameworks: Strategies and Applications in Biocatalysis

“…Most of the COFs reported in the literature have been synthesized using the solvothermal method . In this method of synthesis, the building blocks are solubilized in a solvent or mixture of solvents, commonly containing 1,4‐dioxane and mesitylene, using some acid as catalyst and heating this mixture to temperatures above 100 °C.…”
