title: Ultrasonic irradiation assisted syntheses of one-dimensional di(azido)-dipyridylamine Cu(II) coordination polymer nanoparticles.
abstract: The Cu(II) coordination polymer, [Cu(dpa)(N₃)₂]n (1), has been synthesized by the reaction of 2,2'-dipyridylamine (dpa) and a mixture of Cu(ClO₄)₂·6H₂O and sodium azide under ultrasonic irradiation. The products were characterized by infrared (FT-IR) spectroscopy, X-ray powder diffraction, and scanning electron microscopy (SEM). The CuO nano particles were prepared from calcination of compound 1 at 873 K. The CuO nanoparticles were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM). This study demonstrates that sonochemistry is a suitable method for the preparation of coordination polymer nano-structures and that the calcination temperature can be an effective parameter to control the size of CuO nano-structures prepared by direct calcination of a coordination polymer.
