摘要
红色发光材料一直是有机电致发光中较为稀缺的材料 ,也是电致发光全色显示不可缺少的材料。通过设计和合成得到了一种新型红色电致发光材料 ,( 2 ,2’ 二羟基偶氮苯 ) -( 8 羟基喹啉 )合铝 (Ⅲ ) (Al(azb q) ) ,该材料为一种铝的金属络合物 ,含有两种配体 :8 羟基喹啉和 2 ,2’ 二羟基偶氮苯。实验证明 ,该材料具有较高的热稳定性和较好的成膜特性 ,同时材料本身具有一定的电子传输能力。
Up to date, the red light emitting materials used in organic electroluminescence, which are highly required in full color display, remain rare. A novel red light emitting material, (o,o' dihydroxyazobenzene)(8 quinolinoato) aluminum (Al(azb q)), was obtained. It is an aluminum complex, possessing an o,o' dihydroxyazobenzene ligand and a 8 quinolinoato ligand, bearing a high decomposition temperature of 200℃ and some electron transport ability. The maximum wavelength of the EL emission of Al(azb q) is located around 635nm. The color position in the color coordinates system shows a strong potential as a red light emitting material for organic electroluminescence.
