Mohammad Janghouri Faculty of Industrial Technologies, Urmia University of Technology, P. O. Box: 57155-419, Urmia, Iran. Hamid Abedi Police technology and equipment department, Police Sciences and Social studies Institute, Tehran, Iran Journal Article 2022 10 03 A novel diorganotin(IV) complex, [(SnMe2)2(C15H9O2)(OCH3)(O)]2, with high optical properties was synthesized by an efficient method and fully characterized by elemental analysis and 1H, 119Sn NMR, IR and UV spectroscopies. It should be noted that the anthracene-9-carboxylic acid with high conjugated π-system and acceptable optical properties was utilized as a ligand for the preparation of this complex. The crystal structure of prepared complex was determined by single crystal X-ray diffraction. Crystal structure analysis of prepared compound displays the attendance of a tetranuclear, centrosymmetric dimeric, complex that crystallizes in the triclinic system with the space group of p_1^-. Thermogravimetric analysis (TGA) has been used for the investigation of the thermal behavior of prepared complex. The absorption and photoluminescence properties of the complex were investigated in solid state at room temperature. The investigation of the optical properties of complex shows that this complex can be as a good fluorescent material in the preparation of luminescence devices like light-emitting diodes. The metal complex significantly increased the optical efficiency and current density of the diode. Also, by adding metal to the ligand, the emission wavelength of the organic light emitting diode (OLED) was changed.
