以 8 氨基喹啉为亲水头基合成了两亲配体 2 十二烷基丙二酸二 (8 氨基喹啉 )酰胺 (H2 A)的铜配合物 (CuA)。研究了H2 A、CuA在纯水亚相和H2 A在CuCl2 亚相表面的成膜性能。H2 A与亚相中的Cu2 + 发生配位形成了配合物 (Cu H2 A)。X射线光电子能谱表明 ,H2 A通过氮原子与Cu2 + 配位 ,配位比为 1∶1。CuA的成膜性能最好 ,其次是Cu |H2 A。以H2 A、Cu H2 A和CuA的LB膜制备了三层电致发光器件 :ITO TPD LB膜 Alq3 Al,其起亮电压分别为 7 5、6 7和 6 5V ,最大亮度分别为 63 0、3 5 2和 3 76cd m2 ,电致发光光谱的发射峰分别为 5 0 3、5 1 0和 5 1 4nm。配合物较弱的电致发光性能归因于Cu2 + 的荧光淬灭作用
The copper complex (CuA) of amphipathic ligand di (8-aminoquinoline) amide (H2 A) was synthesized with 8-aminoquinoline as the hydrophilic head group. The film forming properties of H2 A and CuA on the Cu2 + and Cu2 + subphases were studied. H2 A complexed with Cu2 + in the subphase to form a complex (Cu H2 A). X-ray photoelectron spectroscopy shows that H2 A coordinates to Cu2 + through a nitrogen atom with a coordination ratio of 1: 1. The best film formation performance of CuA followed by Cu | H2A. Three layers of electroluminescent devices were fabricated with LB films of H2 A, Cu H2 A and CuA: ITO TPD LB film Alq3 Al with a starting voltage of 7 5, 6 7 and 6 5 V, respectively, and maximum luminances of 63 0, 3 5 2 and 3 76cd m2. The emission spectra of the electroluminescence spectra were 5 0, 35 1 0 and 5 1 4 nm, respectively. The weak electroluminescent properties of the complexes are attributed to the fluorescence quenching of Cu2 +
