Enhanced Proton Conduction in Metal–Organic Frameworks through Single-Crystal to Single-Crystal Transformation

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 13, 2025

In this work, an anionic framework Co-MOF (1) was elaborately constructed, which underwent single-crystal-to-single-crystal (SC-SC) transformation to produce 1-Cr and 1-Fe after immersion in a CrCl3 or FeCl3 solution. Despite the similar crystal structure, significantly enhanced proton conductivities of far exceed that 1 at all humidity temperature conditions. Even 30 °C 98% RH, conductivity can reach up high values 1.49 × 10–2 6.39 10–3 S cm–1, respectively, surpassing by over 5000 times under identical The partial alteration proton-conducting carriers from metal-water cluster [Co(H2O)6]·6H2O] metal-hydroxyl-water clusters [Cr(OH)4(H2O)2]·6H2O] (1-Cr) [Fe(OH)4(H2O)2]·6H2O] (1-Fe) be attributed for above-mentioned performance. introduction hydroxyl SC-SC establish interconnected conduction pathways within channels, greatly facilitate conduction, affording much lower activation energies (0.12 eV 1-Cr, 0.18 1-Fe, 0.28 1). This research demonstrated not only achieved improved but also contributed deeper understanding structure–property relationships, providing new insights into design advanced materials with conductivity.

High Proton Conductivity Enhancement Obtained by a Covalent Postsynthesis Modification Approach for Two Metal–Organic Frameworks

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: March 6, 2025

This study demonstrates an effective strategy to enhance proton conductivity by synthesizing 2 three-dimensional metal-organic frameworks (MOFs), [Zn(DTD22)]n (MOF 1) and [Cd2(DTD22)2]n 2), (DTD22 = 4,4″-diamino-[1,1':4',1″-terphenyl]-2,2″-dicarboxylic acid). The DTD22 ligand used formed a continuous hydrogen-bonding network in the structure, constructing excellent hydrophilic channels. MOF 1 were further postsynthesized modified (PSM) Schiff base reaction, 4-chloro-3-formylbenzenesulfonic acid ligands containing -SO3H -Cl successfully introduced into framework form PSM-MOF 2. Experiments showed that this modification significantly enhanced of materials, especially at 90 °C 98% RH: (2.38 × 10-1 S·cm-1) (3.50 S·cm-1). In comparison, conductivities unmodified 8.55 10-2 S·cm-1 9.50 10-5 S·cm-1, respectively. present MOFs can be effectively covalent postmodification method, which provides new idea for application MOFs.
