Abstract A new mixed-ligand diorganotin(IV) complex, [μ-(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, 1H, 13C and 119Sn 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 P21/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).

一种新型混合配体二有机锡 (IV) 配合物的合成、表征和电致发光特性

摘要 通过二氯化二甲基锡 (IV) 与 1,2-di(4) 反应合成了一种新的混合配体二有机锡 (IV) 配合物 [μ-(4-dpe){Me2Sn(cup)2}2] (1) -吡啶基)乙烯(4-dpe)和N-亚硝基-N-苯基羟胺铵(杯)。制备的配合物通过 PXRD、1H、13C 和 119Sn NMR、IR、UV 光谱和元素分析 (CHN) 进行了充分表征。X射线衍射对配合物1的结构分析表明,该化合物由中心对称双核单元组成,在单斜晶系中结晶,空间群为P21/c。该复合物的热行为在空气气氛下通过热重分析和差热分析(​​TGA 和 DTA)进行了调查。制备的二有机锡(IV)配合物的热行为和发光性能研究表明,该配合物可用作制备光学器件中的发光层。制备的配位化合物以两种不同的浓度用于制造两种发光二极管 (OLED)。
