Through careful consideration of charge matching, a simple replacement of metal ion from Cd 2+ to Ln 3+ in a building unit successfully transforms an anionic microporous framework into a series of isostructural porous neutral heterometallic frameworks [Cd 3 Ln 2 (btc) 4 (H 2 O) 6 (dmf) 4 ]⋅ x (solvent) ( 1 ; Ln=Tb, Eu, Nd, Gd, Sm, dmf= N , N ′‐dimethylformamide) by employing five different lanthanide ions. 1‐Tb and 1‐Eu exhibit interesting photoluminescent properties, and remarkably, 1‐Tb can act as a luminescent sensor to identify organic solvents and metal ions.
