Multi-interpenetration driven ultra-robust ionic HOF with high proton conductivity for DMFCs

Abstract

Herein, a novel ionic hydrogen-bonded organic framework (iHOF-12) was synthesized. The 5-fold interpenetrating network structure and charge-assisted synergistic effects enable iHOF-12 to maintain robustness under demanding conditions and attain excellent proton conductivity of 1.23 × 10⁻² S cm⁻¹, which contributes to the enhancement of the DMFC performance.
