Synthesis, characterization and electroluminescence properties of a new mixed-ligand diorganotin(IV) complex

A new mixed-ligand diorganotin(IV) complex, [mu-(4-dpe){Me2Sn(cup)(2)}(2)] (1), was synthesized by reacting dimethyltin(IV) dichloride with 1,2-di(4-pyridyl)ethylene (4-dpe) and ammonium N-Nitroso-N-phenylhydroxylamine (cup). The prepared complex was fully characterized by PXRD, H-1, C-13 and Sn-119 NMR, IR, and UV spectra and elemental analysis (CHN). The structural analysis of complex 1 by X-ray diffraction showed that this compound consists of centrosymmetric binuclear units that crystallize in the monoclinic system with the space group of P2(1/c). Thermal behavior of this complex was interrogated by thermogravimetric and differential thermal analysis (TGA and DTA) under air atmosphere. The study of thermal behavior and luminescence properties of prepared diorganotin(IV) complex exhibited that this complex can be used as a emitting layer in the preparation of optical devices. The prepared coordination compound was used in two different concentrations in the manufacture of two light-emitting diodes (OLEDs).
