A new class of lanthanide luminescent MOFs was constructed by encapsulating Ln3+ into the pores of MIL-121 (Ln3+@MIL-121). Ag+ was found to be able to greatly enhance the weak visible or NIR luminescence of Ln3+@MIL-121 since it can induce more efficient intramolecular energy transfer from the ligand to Ln3+ in Ag–Ln co-doped MOFs.

Luminescent Behavior

Luminescent mixed lanthanide metal−organic framwork (MOF) materials have been prepared from two polyheterocyclic diacid ligands, 2,6-bis(3-carboxy-1-pyrazolyl)pyridine and 2,6-bis(4-carboxy-1-pyrazolyl)pyridine. The crystal structures of the two organic molecules are presented together with the structures for the MOFs obtained by hydrothermal synthesis either with Yb(III) or mixed Tb(III)/Yb(III) ions. Different coordination architectures result from each ligand, revealing also important differences between the lanthanides. The mixed lanthanide metal−organic frameworks also present diverse luminescent behavior; in the case of 2,6-bis(4-carboxy-1-pyrazolyl)pyridine, where no coordinated water is present in the metal environment, Tb(III) and Yb(III) characteristic emission is observed by excitation of the bispyrazolylpyridine chromophore.
