Abstract

Abstract : The deliberate introduction of defects on fcu frameworks, based on Ni8 clusters connected by benzenebipyrazolate linkers, after the treatment with KOH/EtOH leading to missing linker defects and metal cluster basification, is responsible for a boosting of the ion conductivity and depletion of activation energy barrier for the mobility of hydroxide ions. It is worth noting that framework hydrophilicity also plays a major role in order to establish water‐mediated proton‐transfer processes from the basic [Ni8 (OH)5 (EtO)] clusters to the hydration water molecules (Grotthuss mechanism).
