Theoretical hydrogen bonding calculations and proton conduction for Eu(iii)-based metal–organic framework

Abstract

A water-mediated proton-conducting Eu(III)-MOF has been synthesized, which provides a stable proton transport channel that was confirmed by theoretical calculation. The investigation of proton conduction shows that the conductivity of Eu(III)-MOF obtained at 353 K and 98% RH is 3.5 × 10⁻³ S cm⁻¹, comparable to most of the Ln(III)-MOF based proton conductors.
