Abstract

Three novel praseodymium−adipate frameworks were synthesized hydrothermally. GWMOF-3 ([Pr₂(adipic acid)₃(H₂O)₄]·adipic acid·4H₂O) and GWMOF-6 ([Pr₂(adipic acid)₃(H₂O)₂]·4,4‘-dipyridyl) formed three-dimensional structures, whereas GWMOF-4 ([Pr₂(adipic acid)₃(H₂O)₂]·H₂O) produced a more dense, two-dimensional topology. Single-crystal X-ray and powder diffraction, IR spectroscopy, fluorescence spectroscopy, thermogravimetric analysis, and elemental analysis were employed to characterize all samples. GWMOF-6 represents an innovative step forward in metal−organic framework synthesis where a neutral molecular species not used in the construction of the framework is utilized as a structure-directing agent, or template. Furthermore, this template molecule (4,4‘-dipyridyl) is shown to sensitize the fluorescence of lanthanide metal centers in a europium analogue of GWMOF-6.
