Overview

This research develops high proton conductivity in polyoxometalate-based metal-organic frameworks, suggesting specific acid dissociation constants play a key role.

Key Points

  • CUST-835 achieved a proton conductivity of 2.06 × 10-4 S cm-1 under humidified conditions at 90 °C.
  • DFT calculations confirmed pKa values for POMs, correlating strongly with measured proton conductivities.
  • Synthesis involved hydrothermal methods to generate isostructural POMOFs from Anderson-type polyoxometalates.
  • AC impedance studies indicate significant variation in proton conductivity between two synthesized frameworks.
