Abstract
A Mg(II)-based coordination polymer was synthesized by a solvothermal reaction between Mg2+ and 2,5-dimercaptoterephthalic acid (H4dmtp) in N,N-diethylformamide (DEF). The thiol (─SH) groups in the H4dmtp ligand were oxidized to form the sulfinato (─SO2−) groups, which were structurally stabilized through coordination to the Mg2+ centers. The temperature-dependent proton conductivities exhibited relatively low activation energy (0.19 eV) for proton transfer, suggesting that the hydrogen-bonded networks formed by the water molecules and the sulfinato oxygen atoms produced efficient proton-hopping pathways.
