High proton conductivity in an unprecedented anionic metalloring organic framework (MROF) containing novel metalloring clusters with the largest diameter

Abstract

An attractive anionic metalloring organic framework (MROF-1) containing unprecedented sextuply interlocked nanocages made up of original metalloring clusters with the largest diameter of ca. 21 Å shows a high proton conductivity up to 1.72 × 10⁻² S cm⁻¹ at 70 °C and 97% RH, owing to plenty of counter cations (Me₂NH₂)⁺ located in the 1D channels.
