Ultrasound irradiation effect on morphological properties of a 3D nano zinc(II) supramolecular coordination polymer.

Nano-structures of [Zn(L)(atpt)] n ( 1 ) (L = 1,2-bis(2-methylbenzimidazol-1-ylmethyl)benzene and H 2 atpt = 2-aminoterephthalic acid) were obtained by hydrothermal and sonochemical approaches, characterized by scanning electron microscopy (SEM), IR, powder X-ray diffraction (PXRD), and elemental analysis. CP 1 features a 2D (4,4) network with the point symbol {4 4 .6 2 }, the 3D supramolecular architecture in CP 1 is controlled through π ⋯ π stacking interactions. The influence of various concentrations of initial reagents, power of ultrasound irradiation, and ultrasound time on the morphology and size of nano-structured CP 1 were studied in detail. In addition, the luminescence and photocatalytic properties of the nanoparticles of CP 1 for the degradation of methyl blue (MB) have also been investigated. [ABSTRACT FROM AUTHOR]
