A novel mesoporous hydrogen-bonded organic framework with high porosity and stability

Abstract

A highly chemically and thermally stable mesoporous hydrogen-bonded organic framework with a high surface area and a large pore volume has been rationally designed and constructed.

Construction of isostructural hydrogen-bonded organic frameworks: limitations and possibilities of pore expansion

“…28,29 Farha's, Chao's, and Chen's groups independently reported pyrene-based isostructural HOFs based on pyrene derivatives with different substituents (carboxy, 4carboxyphenyl, and 6-carboxynaphthalen-2-yl). 19,30,31 Miljanić and coworkers also reported a series of quasi-isotropic fluorinated honeycomb HOFs. 32,33 The weakness of H-bonds is clearly behind the low number of isostructural HOF families.…”

Protein-directed, hydrogen-bonded biohybrid framework

“…This should increase the protein incorporation in the biohybrids. With this in mind, we chose H4PTTNA 51 as the alternative linker (Figure S27). H4PTTNA has a larger p-conjugated system than H4TBAPy, and the strong deprotonation effect was substantiated by calculation that specifically compared the pK a values of H4PTTNA and H4TBAPy, which predict that H4PTTNA (pK a = 6.61, Table S1) is more acidic than H4TBAPy (pK a = 6.90).…”

A Microporous Hydrogen‐Bonded Organic Framework for the Efficient Capture and Purification of Propylene

“…To examine the potentials of HOFs for the challenging C 3 H 6 /C 3 H 8 separation, we compared HOF-16 with other five HOFs (HOF-BTB, [20] HOF-11, HOF-14, [21] PFC-1 [22] and HOF-TCBP [23] )t os tudy their C 3 H 6 and C 3 H 8 adsorption properties.A ll the other selected HOFs are based on hydrogen-bonded carboxylic acid dimers,w ith large pore S15). In contrast, the C 3 H 6 and C 3 H 8 uptake capacities of HOF-11 isomer is 62.3 and 56.0 cm 3 g À1 , respectively,at298 Kand 1bar (Figure S12a), showing alow C 3 H 6 /C 3 H 8 uptake difference (by 11 %).…”
