High surface area andZ′ in a thermally stable 8-fold polycatenated hydrogen-bonded framework

Abstract

1,3,5-Tris(4-carboxyphenyl)benzene assembles into an intricate 8-fold polycatenated assembly of (6,3) hexagonal nets formed through hydrogen bonds and π-stacking. One polymorph features 56 independent molecules in the asymmetric unit, the largest Z' reported to date. The framework is permanently porous, with a BET surface area of 1095 m(2) g(-1) and readily adsorbs N2, H2 and CO2.

Selective separation of Xe/Kr and adsorption of water in a microporous hydrogen-bonded organic framework

“…Nevertheless, the synergistic effect of multiple hydrogen bonding and p-p stacking between organic linkers in the HOF's building unit makes it stable even aer the removal of guest solvent molecules or even in an aqueous environment. 3,4 Over the past decade, they have attracted increasing interest with their applications including gas adsorption and separation, [5][6][7][8] proton conduction, 9 and sensing. 10 Aer the rst discovery of Kr and Xe in the late 19th century, the exploitation of these 'noble' gases has widely expanded from small bulbs, display, and laser industry to state-of-art machinery, medical instruments, and space industry.…”

Self-assembly of two robust 3D supramolecular organic frameworks from a geometrically non-planar molecule for high gas selectivity performance

“…10,[13][14][15][16][17][18][19] However, the stability of SOFs is still a challenge although a number of SOFs with permanent porosity have been reported. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] Considering their highly predictable hydrogenbonding motif, some (carboxylic acid)-containing organic units were selected to construct SOF materials by the groups of Zentner, Moorthy, Hisaki and others. 24,[36][37][38][39][40][41] The vast majority of these SOFs are 2D materials due to the limited propagation ability of planar blocks.…”
