Arylsulfonate Ionic Hydrogen-Bonded Organic Frameworks Enable Highly Stable and Superprotonic Conductivity for Enhancing Direct Methanol Fuel Cells

ACS Materials Letters, Journal Year: 2024, Volume and Issue: unknown, P. 3351 - 3357

Published: June 28, 2024

Developing proton-conducting materials with superior proton conductivity and excellent stability plays an indispensable role in the advancement of direct methanol fuel cells (DMFCs). In this work, we successfully synthesized ionic hydrogen-bonded organic framework (iHOF-13) 3D hydrogen-bonding network structures. The inherent abundance hydrogen bonding networks HOFs enables them to exhibit superprotonic conductivity. Specifically, iHOF-13 demonstrates a 1.3 × 10–1 S cm–1 at 98% relative humidity 100 °C. iHOF is enriched transport sites, its doping into Nafion matrix exhibits extremely high (10–1 cm–1) low permeability. maximum power density 7.5%-iHOF-13/Nafion composite membrane can reach 104.7 mW cm–2 DMFCs, which 2.1 times higher than that recast Nafion. incorporation high-performance facilitates enhancement pathway while effectively inhibiting crossover, thus expanding potential application cells.

Freestanding Hydrogen‐Bonded Organic Framework Membrane for Efficient Wound Healing

Advanced Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 3, 2024

Abstract Hydrogen‐bonded organic frameworks (HOFs) are emerging as multifunctional materials with exceptional biocompatibility, abundant active sites, and tunable porosity, which highly beneficial for advanced wound care. However, a significant challenge involves transforming pristine HOFs powders into lightweight, ultrathin, freestanding membranes compatible soft biological systems. Herein, the study successfully develops shape‐adaptive HOF‐based matrix (HMMs) using polymer‐assisted liquid‐air interface technique. The HMMs conform seamlessly to tissues of different sizes shapes, effectively stopping bleeding, provide high water‐vapor permeability. Notably, both in vitro vivo studies mice models demonstrated that these tissue‐conformable significantly accelerate healing by modulating inflammatory environment injured tissue promoting rapid re‐epithelialization. Furthermore, RNA‐seq analysis mechanistic revealed reduce inflammation facilitate transition from proliferative stage remodeling skin development. This work not only opens up new avenues care but also establishes foundation hybridizing polymers wide range potential applications.

Dual Free Radical Synergism for Enhancing Proton Conductivity in Photochromism iHOFs

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

Published: Feb. 20, 2025

Stimuli-responsive smart materials, as an emerging material, can fulfill reversible transformation of chemical/physical properties under external stimuli such mechanical stress, light, and electricity, which has the highlights rapid response, designable structure, function. Two ionic hydrogen-bonded organic frameworks (iHOFs 36–37) were synthesized by self-assembly bis(benzene-o/p-sulfonic acid)-naphthalenediimide (o/p-H2BSNDI) two basic ligands. The naphthalenediimide (NDI) was introduced into material to equip iHOFs 36–37 with radical-driven photochromic behavior. proton conductivity iHOF-37 demonstrated a maximum 6.50 × 10–4 S·cm–1 at 98% RH 100 °C, it increased 9.10 10–3 due dual free radical synergism following UV irradiation (NDI viologen), represents significant 14-fold enhancement. Furthermore, incorporation chitosan (CS) matrix forms composite membranes. 5%-iHOF-37/CS membrane reached up 5.70 10–2 90 8.08 after irradiation. This work reveals radicals generated NDI viologen derivatives, whose synergistic action plays role in enhancing membranes, rendering rational design stimuli-responsive materials feasible.
