Materials with high proton conductivity have attracted significant attention for their wide-ranging applications in exchange membrane fuel cells. However, the design of new and efficient porous proton-conducting materials remains a challenging task. The structure-controllable highly stable metal phosphates can be synthesized into layer or frame networks to provide transport capabilities. Herein, we successfully three isomorphic phosphovanadates, namely, H2(C2H10N2)2[MII(H2O)2(VIVO)8(OH)4(PO4)4(HPO4)4] (C2H8N2 = 1,2-ethylenediamine; M Co, Ni, Cu), by hydrothermal method employing ethylenediamine as template. These pure inorganic open frameworks exhibit cavity width ranging from 6.4 7.5 Å. Remarkably, compounds 1–3 reach 1 × 10–2 S·cm–1 at 85 °C 97% relative humidity (RH), they remain temperatures well long-term stability. This work provides novel strategy development materials.

Post Synthetic Modification (PSM) of Metal-Organic Frameworks (MOFs) is a crucial strategy for developing new MOFs with enhanced functional properties compared to their parent one. PSM can be accomplished through various methods:1) modification organic linkers; 2) exchange metal ions or nodes; and 3) inclusion solvent/guest molecules. Herein, bimetallic monometallic containing biphenyl dinitro-tetra-carboxylates (NCA) are demonstrated. The tetra carboxylate NCA, produces Cd-MOF-1 Cu-MOF-1 CoZn-MOF in solvothermal reactions the corresponding salts. undergoes post-synthetic transmetallation Cd(NO
