【 摘 要 】

To prepare a new tin(IV) complex (1), [(SnMe2)2(C15H9O2)(OCH2CH3)(O)]2, with strong optical absorption, anthracene-9-carboxylic acid (HL) with a large conjugated π-system and rich optical properties has been used as a ligand. The characterization of title complex was performed by various spectroscopic methods, including 1H NMR, 13C NMR, 119Sn NMR, UV, IR, and elemental analyses (CHN). The crystal structure of complex 1 was determined by single-crystal X-ray diffraction. The results of spectroscopic data along with structural analyses showed that complex 1 is a tetranuclear, centrosymmetric dimeric and contains two Sn atoms, one in a five-coordinate environment and the other in a six-coordinate environment. Thermogravimetric and differential thermal analyses (TGA and DTA) have been used to study the thermal behavior of 1. The investigation of photoluminescence properties and thermal behavior of complex 1 showed that this compound has the necessary conditions for its use as a precursor in the manufacture of optical devices. This compound was used as an emitting layer for the preparation of an organic light-emitting diode. The effect of the complex concentration on the electrical properties of the diode was investigated.
