Abstract
A new zinc(II) complex (Mq-H)[ZnCl2(Mq)]·C2H5OH, was prepared and characterized by 1H NMR, IR, and UV spectroscopy and elemental analysis in addition to single-crystal X-ray diffraction. The nanostructure of the complex was also successfully prepared at room temperature by a facile and environment-friendly sonochemical method. This new nanostructure was characterized by scanning electron microscopy, X-ray powder diffraction, IR spectroscopy, and elemental analysis. The photoluminescence properties of the nanostructured and bulk crystalline of the prepared complex in the solid state were investigated in detail at room temperature. The results indicated that the size of the complex particles has an important effect on the optical properties of it. The nano-zinc(II) complex displayed higher photoluminescence intensity and quantum yield than the zinc(II) complex as single crystal. Both absorption and emission peaks of the nano-complex red shifted significantly in comparison with that of as single crystal.
