Pyrolytic synthesis and luminescence of porous lanthanide Eu-MOF

A lanthanide metal coordination polymer [Eu 2 (BDC) 3 (DMSO)(H 2 O)] was synthesized by the reaction of europium oxide with benzene-1,3-dicarboxylic acid (H 2 BDC) in a mixed solution of dimethyl sulfoxide (DMSO) and water under hydrothermal conditions. The crystal structure of Eu 2 (BDC) 3 (DMSO)(H 2 O) was characterized by X-ray diffraction (XRD). Thermo-gravimetric analysis of Eu 2 (BDC) 3 (DMSO)(H 2 O) indicated that coordinated DMSO and H 2 O molecules could be removed to create Eu 2 (BDC) 3 (DMSO)(H 2 O)-py with permanent microporosity, which was also verified by powder XRD (PXRD) and elemental analysis. Both Eu 2 (BDC) 3 (DMSO)(H 2 O) and Eu 2 (BDC) 3 (DMSO)(H 2 O)-py showed mainly Eu-based luminescence and had characteristic emissions in the range 550–700 nm. Copyright © 2015 John Wiley & Sons, Ltd.
