Sonochemical synthesis of a nano-structured zinc(II) amidic pillar metal-organic framework

A facile and environmentally friendly nano-scale synthesis of a Zn(II) metal-organic framework (MOF), {[Zn4(BDC)4(bpta)4]·5DMF·3H2O}n (1) (bpta=N,N'-bis(4-pyridinyl)-1,4-benzenedicarboxamide, BDC=1,4-dicarboxylate, DMF=N,N-dimethylformamide), with nanorods morphology under ultrasonic irradiation at ambient temperature and atmospheric pressure has been explored. This MOF has been characterized by scanning electron microscopy (SEM), powder X-ray diffraction (PXRD) and IR spectroscopy. Some parameters such as concentration of initial reagents, power ultrasound irradiation and time effects on size and morphology of nano-structured compound 1 have been studied.
