abstract = {A family of metal–organic frameworks with general formula {[Nd2(ant)2((NH2)2‐
bdc)(DMF)4]∙2DMF}n (1) and {[Ln2(ant)2((NH2)2‐bdc)(DMF)4]∙2DMF∙2H2O}n (Ln = Tb (2), Ho (3), and
Er (4)) has been obtained from reactions between 9,10‐anthracenedicarboxylic (H2ant) and 2,5‐dia‐
minoterephthalic ((NH2)2‐H2bdc) acids, and lanthanide ions in dimethylformamide (DMF). These
lanthanide–organic frameworks (LnOFs) have been characterized, and their crystal structures have
been elucidated by single crystal and powder X‐ray diffraction methods (on the basis of a compar‐
ative refinement with similar structures), respectively for 1 and 2–4. All LnOFs present three‐di‐
mensional structures composed of dinuclear [Ln2(μ‐CO2)4] entities linked through both carboxylate
ligands that yield open frameworks in which DMF and water molecules are located in the channels.
Magnetic studies of these LnOFs have revealed slow relaxation of the magnetization for the Nd‐
based counterpart. The compounds also acknowledge relevant photoluminescence (PL) emissions
in the visible (for the Tb‐based homologue) and near‐infrared (for the Nd‐  and Er‐based com‐
pounds) regions. The strong green emission yielded by compound 2 at room temperature allows its
study for photoluminescence (PL) sensing of various solvent molecules, finding a particular dis‐
crimination for acetone.},
