【摘要】 8-羟基喹啉铝配合物是用于有机电致发光材料的金属配合物,是目前平板显示领域的研究热点,相比于液晶显示技术,具有耗能低、主动发光、亮度高、高对比度、响应速度快等优点。近二十年来,有机电致发光材料和器件的研究工作取得了长足进步,其主要技术指标已经接近或达到实际应用的要求。通过化学修饰的方法来调控8-羟基喹啉铝类配合物的发光光谱,这对于拓展有机电致发光材料的应用范围,优化器件的性能都有着重要的实际应用价值,本文通过化学修饰,合成了5-羟甲基-8-羟基喹啉（Oq）,其结构经红外光谱、核磁氢谱分析的表征,进一步合成了8-羟基喹啉铝（Alq₃）（1）及其衍生物:混合配体配合物Al（Oq）q₂（2）、混合配体配合物Al（Oq）₂q（3）和5-羟甲基-8-羟基喹啉铝（Al（Oq）₃） （4）四种配合物。并通过红外光谱、紫外光谱的表征,测定其发光性质。为其进行电致发光器件制备及性能的研究提供了理论依据。经过化学修饰后的配合物通过荧光光谱的分析,与8-羟基喹啉铝相比,最大发光波长均发生红移。随着5-羟甲基-8-羟基喹啉量的变大化,最大发光波长也继续红移。此外,成功合成并培养了一种未见文献报道的吡啶-2,3,5,6-四甲酸与锌（II）的配合物单晶,采用X-ray单晶衍射技术,测定并解析了其单晶结构,对配合物的红外光谱和荧光光谱性质进行了研究。配合物属于单斜晶系,P2（1）/m空间群,分子间通过碱金属的参与,架构出三维立体网状结构。研究了配体在配合物中的配位模式。配合物K₂Zn₃（PTA）₂·10.5H₂O具有荧光性。更多还原

【Abstract】 Tris(8-Hydroxylquinoline) aluminium compounds are broadly applied in the eletroluminescene(EL) materials which is the hot-topic research in the flat-panel display fields. Compared with the liquid crystal display technique, It is advantageous as follows: lower consumption, active luminescence, higher Brightness and higher contrast. In recent twenty years, the research of eletroluminescent materials and equipments have made remarkable strides. Its main technical specifications have achieved or are approaching the requirement of the practical application.The emission spectrum of tris(8-Hydroxylquinoline) aluminium compounds were mediated by chemical modification. This approach has made important practical application value to enrich the application range of the eletroluminescene materials and optimize the eletroluminescene equipments. In these studies 5-hydroxylmethyl -8-quinoline was synthesized by chemical modification, also characterized by IR spectrum and H1NMR analysis. And further synthesized tris(8-Hydroxylquinoline) aluminium (1) and its derivatives: mixed compound (2), mixed compound (3) and tris(5-hydroxylmethyl-8-Hydroxylquinoline) aluminium (4), also characterized by IR spectrum and ultraviolet spectrum analysis, and analysis its luminescent properties. They provide new experiment base for the further study in the preparation of the eletroluminescent equipments.After analysised the emission spectrum of the compounds, all the max luminescent wavelengths are red shifted compared with tris(8-Hydroxylquinoline) aluminium. And the extent of the red shifts of the max wavelengths would be change as the amount of 5- hydroxylmethyl-8-Hydroxylquinoline is increased.In addition, A new potassium pyridine-2,3,5,6-tetracarborxylate zinc (II) compound has been synthesized, characterized by IR spectrum, ultraviolet spectrum analysis and single-crystal X-ray diffraction. The compound crystallize in the monocline space group P2(1)/m. Through the participation of the potassium ion in the molecules, It frames a three dimensional structures of coordination complex. The metal ion in the coordinated patterns of the compounds is analysised. The complex potassium pyridine-2,3,5,6-tetracarborxylate zinc (II) shows photoluminescence properties.更多还原
