Synthesis and characterization of a new tin(IV) complex for fabrication of an organic light-emitting diode (OLED) and photoluminescence properties of the tin oxide core

A new tin(IV) complex, (C13H10NO)[SnCl4(C9H6NO)]<bold>2</bold>CH3OH, was prepared in a facile process and characterized by H-1, C-13, and Sn-119 NMR, IR, and UV spectroscopy in addition to single-crystal X-ray diffraction analysis. Current-voltage (I-V) characteristics, photoluminescence (PL), and electroluminescence (EL) properties of the complex have been investigated and an application of the prepared complex in fabrication of an organic light-emitting diode has been demonstrated. The EL of the compound exhibits blue-green emission at 494nm. Tin(IV) oxide core that resulted from direct thermal decomposition of the complex at 450 degrees C in air was characterized by X-ray powder diffraction and scanning electron microscopy; then, the PL property was investigated and compared with the PL of the complex. The tin(IV) oxide core showed a band gap of approximate to 3.81eV determined from the UV/visible absorption spectrum. The tin oxide core showed stable PL with one emission peak centered at 581nm.
