NbO lattice MOFs based on octahedral M(II) and ditopic pyridyl substituted diketonate ligands: structure, encapsulation and guest-driven luminescent property

Two NbO-type MOFs based on ditopic pyridyl substituted diketonate ligands were reported. One exhibits a reversible SC-SC water encapsulation, while the other shows an interesting guest-driven luminescent property based on M(III) acetylacetonate (M = Eu and Fe) guest species.
