Abstract

We observed an ordered-to-disordered structural transformation in a Cu2+ coordination polymer and investigated its influence on the proton conductivity. The transformation generated highly mobile proton carriers in the structure. The resulting material exhibited a conductivity greater than 10−2 S cm−1 at 130 °C. The structural transformation and the conduction mechanism were investigated by EXAFS, TPD-MS and NMR.
