Abstract

Introducing sulfonic acid groups into MOF materials is one of the effective approaches to enhance proton conduction. Here, we attempted to prepare a new post-modified ZIF-90-based material by addition reaction of the aldehyde group with bisulfite to obtain partially functionalized ZIF-90-SO <subscript>3</subscript> Na <subscript>(2.3)</subscript> . ZIF-90-SO <subscript>3</subscript> Na <subscript>(2.3)</subscript> exhibits a high proton conductivity of 2.26 × 10 <superscript>-2</superscript> S cm <superscript>-1</superscript> at 98% RH and 100 °C.
