Ultrasound assisted synthesis of a Zn(II) metal-organic framework using non-linear dicarboxylate and linear N-donor ligands

Nano-rods of a 3D, porous Zn(II)-based metal-organic frameworks [Zn(oba)(4-bpdh)0.5]n·(DMF)1.5(TMU-5) was prepared by a sonochemical process and characterized by scanning electron microscopy, X-raypowder diffraction and IR spectroscopy. This MOF was synthesized using a non-linear dicarboxylate (H2oba= 4,4-oxybisbenzoic acid) and linear N-donor (4-bpdh = 2,5-bis(4-pyridyl)-3,4-diaza-2,4-hexadiene) ligandsby ultrasonic. Sonication time and concentration of initial reagents effects on size and morphology of nanostructuredMOF, were also studied. Moreover, calcination of TMU-5 at 550 ºC under air atmosphere yieldsZnO nanoparticles.
