Ultrasound and modulation assisted synthesis of {[Cu2(BDC-NH2)2(dabco)]DMF.3H2O} nanostructures; New precursor to prepare nanorods and nanotubes of copper(II) oxide

• Nanostructures of {[Cu2(BDC-NH2)2(dabco)]DMF.3H2O} were prepared by sonochemical method.
• Coordination modulation method was coupled by ultrasound to growth the nanorods.
• Acetic acid was used as a modulator reagent because of same functionality as a linker.
• {[Cu2(BDC-NH2)2(dabco)]DMF.3H2O} precursor is calcinated at 500 °C for 1 h to prepare CuO nanostructures.

Nanostructures of porous coordination polymer {[Cu2(BDC-NH2)2(dabco)]DMF.3H2O} (1) have been synthesized in the presence of acetic acid as a modulator via sonochemical method. Different concentrations of metal ions, organic linkers, modulator reagent and also different sonication times were held to improve the quality and distribution of nanostructures. Ultrasound irradiation helps to nucleation step of the oriented attachment of modulation method and nanorods of compound 1 has been prepared. Compound 1 was calcinated at 500 °C to prepare nanorods and nanotubes of copper(II) oxide. Compound 1 and CuO nanostructures were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HR-TEM), X-ray powder diffraction (XRD) and thermal gravimetric analysis (TGA).
