title: Nanoparticles of novel organotin(IV) complexes bearing phosphoric triamide ligands.
abstract: Four novel organotin(IV) complexes containing phosphoric triamide ligands were synthesized and characterized by multinuclear ((1)H, (31)P, (13)C) NMR, infrared, ultraviolet and fluorescence spectroscopy as well as elemental analysis. The (1)H NMR spectra of complexes 1-4 proved that the Sn atoms adopt octahedral configurations. The nanoparticles of the complexes were also prepared by ultrasonication, and their SEM micrographs indicated identical spherical morphologies with particles sizes about 20-25 nm. The fluorescence spectra exhibited blue shifts for the maximum wavelength of emission upon complexation.
