Series of Microporous Redox‐Active Pillared Metal–Organic Frameworks Based On Alloxazine Ligands
Year: 2025
Type: article
Abstract: Two series of robust pillared metal–organic frameworks (MOFs) are obtained under solvothermal conditions by combining a metal salt with either H 2 bpdc , biphenyl‐4,4′‐dicarboxylic acid, or H 2 pda , 1,4‐phenylenediacrylic acid, forming 2D layers, which are pillared by L , an alloxazine derivative of 1,4‐di(pyridin‐4‐yl)benzene using a one‐pot three‐component strategy. Crystallographic studies reveal the formation of two isomorphous series of compounds, namely 1‐M (from H 2 bpdc with M = Co, Ni, Cu, and Zn) and 2‐M (from H 2 pda with M = Co or Cu). The multifunctional compounds have high decomposition temperatures, and their sorption properties were measured, revealing relatively low surface areas. Furthermore, 1‐Zn displays a moderate uptake of CO 2 and C 2 H 4 at high pressures . In addition, for 1‐M (M = Co, Cu or Zn), solid‐state electrochemistry reveals redox behavior for the MOF, centered on the ligand. This study provides evidence for the first account of a one‐pot formation of redox‐active pillared MOFs, which exhibit gas sorption abilities before the reduction.
