Ultrasonic-assisted synthesis of copper(II) azo coordination polymers, new precursors for direct preparation of metalic copper nano-particles

Nanostructures of coordination polymers, (CuL1). 0.5DMF. 0.5EtOH. 1.5H2O (1), and (Cu(L2)2) (2), have been synthesized by the reaction of H2L1 and HL2 with Cu(OAc)2.H2O by sonochemical process. CuO nanostructures were synthesized from calcination of compounds 1-2 nanostructures. Metalic copper nanoparticles were prepared by direct calcination of compounds 1-2 in surfactant at 180 °C.
