Porous hydrogen-bonded organic frameworks (HOFs): From design to potential applications

Atoms and the void: modular construction of ordered porous solids

“…These insights have triggered the explosive development of new post-zeolitic materials with unprecedented porosity, including metal-organic frameworks (MOFs) [20][21][22] , covalent organic frameworks (COFs) [23][24][25][26][27][28] , and hydrogen-bonded organic frameworks (HOFs) [29][30][31][32] . Much of this work has been carried out during the last decade.…”

Monolayer nanosheets formed by liquid exfoliation of charge-assisted hydrogen-bonded frameworks

“…Hydrogen-bonded organic frameworks (HOFs) are a class of porous supramolecular materials assembled through intermolecular hydrogen-bonding interactions. 41,42 Like MOFs and COFs, in order to create porous structures these materials typically rely on rigid aromatic linkers and strong directional hydrogen-bonding groups. HOFs possess a distinct set of properties in comparison to most other framework materials, including ease of synthesis, solution processability, and selfhealing.…”

Coordination-bond-directed synthesis of hydrogen-bonded organic frameworks from metal–organic frameworks as templates

“…These merits stimulate the studies of HOFs as a multi-functional platform in the area of gas storage and separation, molecular recognition, electric/optical materials, chemical sensing, catalysis, and biomedicine. [1][2][3][4][5][6][7][8] Although different methods have been explored to synthesize HOFs including slow solvent evaporation, [9][10] diffusion, [11][12][13] and solvothermal method, 14 the controllable synthesis of HOFs remains a challenge. Due to the inherently weak hydrogen bond interactions, the formation of HOFs by self-assembly is subject to the influence of other competing van der Waals force (such as π•••π and σ••π interactions) between ligands and solvent molecules.…”
