A tetranuclear Cu4(μ3-OH)2-based metal–organic framework (MOF) with sulfonate–carboxylate ligands for proton conduction†
Abstract
A new tetranuclear Cu4(μ3-OH)2-based metal–organic framework (MOF) with sulfonate–carboxylate ligands features large hydrophilic channels. This MOF exhibits proton conductivity over 10−3 S cm−1 at 85–100 °C and 98% relative humidity and colossal dielectric constant.
