Hydrogen-bonded organic frameworks (HOFs) are a rising class of promising proton-conducting materials. However, they always suffer from the inherent contradiction between chemical stability and proton conduction. Herein, inspired by self-assembly lipid bilayer membranes, series aminomethylphosphonic acid-derived single-component HOFs successfully developed with different substituents attached to phosphonate oxygen group. They remain highly stable in strong acid or alkaline water solutions for one month owing presence charge-assisted hydrogen bonds. Interestingly, absence external carriers, methyl-substituted phosphonate-based HOF exhibits very high conductivity up 4.2 × 10-3 S cm-1 under 80 °C 98% relative humidity. This value is not only comparable that consisting mixed ligands but also highest reported HOFs. A combination single-crystal structure analysis density functional theory calculations reveals attributed strengthened H-bonding interactions positively charged amines negatively groups channel bio-inspired finding demonstrates well-defined molecular conductors great importance precise understanding relationship property.

Pore Modulation of Hydrogen‐Bonded Organic Frameworks for Efficient Separation of Propylene

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(37)

Опубликована: Июль 24, 2023

Developing hydrogen-bonded organic frameworks (HOFs) that combine functional sites, size control, and storage capability for targeting gas molecule capture is a novel challenging venture. However, there lack of effective strategies to tune the network achieve high-performance HOFs. Here, series HOFs termed as HOF-ZSTU-M (M=1, 2, 3) with different pore structures are obtained by introducing structure-directing agents (SDAs) into hydrogen-bonding tetrakis (4-carboxyphenyl) porphyrin (TCPP). These have distinct space configurations channels ranging from discrete continuous multi-dimensional. Single-crystal X-ray diffraction (SCXRD) analysis reveals rare diversity models dominated SDAs. HOF-ZSTU-2, which forms strong layered ammonium (NH4+ ) through multiple carboxyl groups, has suitable 1D "pearl-chain" channel selective propylene (C3 H6 ). At 298 K 1 bar, C3 density HOF-ZSTU-2 reaches 0.6 kg L-1 , representing one best materials, while offering propylene/propane /C3 H8 selectivity 12.2. Theoretical calculations in situ SCXRD provide detailed binding strength at locations pearl-chain channel. Dynamic breakthrough tests confirm can effectively separate multi-mixtures.
