A Metal–Organic Framework to CuO Nanospheres of Uniform Morphology for the Synthesis of α-Aminonitriles under Solvent-Free Condition along with Crystal Structure of the Framework

Abstract

Herein, we have reported the synthesis, crystal structure, thermogravimetric property, and photoluminescence activity of a new Cu-based metal organic framework (MOF): {[Cu2(2,5-pdc)2(ald-4)(H2O)2]·3H2O,MeOH}n (where 2,5-pdc = 2,5-pyridine-dicarboxylate, ald-4 = aldrithiol-4) along with catalytic activity of CuO nanoparticles (Cu-NPs) derived from the MOF for green synthesis of organic molecules having biological relevance. The regular arrangement of metal centers and the presence of oxygen and carbon in metal–organic frameworks (MOFs) enable us to utilize them as template/precursor for the synthesis of monodispersed metal-oxide and metal-carbide nanoparticles having a high surface area with well-defined and uniform morphology. The MOF derived oxide nanoparticles generally exhibit improved catalytic activities and product selectivity and significantly reduce the chemical waste production. The structural analysis has revealed that in the complex under investigation the 2,5-pdc bridges the Cu(II) centers to ...
