Abstract

Among the various types of solid-state proton conductors (SSPCs), metal–organic frameworks (MOFs) have emerged as significant importance in the field of proton-exchange membrane fuel-cell (PEMFCs) applications. Herein, we have synthesized a three-dimensional trinuclear zinc-based metal–organic framework, denoted as Zn-SDC-MOF by modification of reported synthetic conditions, where stilbenedicarboxylic acid (H₂SDC) and 4,4′-bipyridine (bpy) are employed as an organic linker unit. With motivation of air stable trinuclear Zn-SDC MOFs, we have analyzed the water stability behavior of this compound. It resulted in exceptional water stability performance over 3 weeks as confirmed by powder X-ray diffraction (PXRD) analysis. Moreover, this MOF compounds have shown modest proton conductive performance of 0.8 × 10⁻³ S cm⁻¹, at 95% relative humidity (RH) and 298 K.
