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

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.
