新型含噻吩基8-羟基喹啉锌配合物的合成及光电性能
Synthesis and Photoelectricity of Novel Zn Metal Complex Based on 8-Hydroxyquinoline with Thiophene Group
摘要
Abstract
8-Hydroxyquinoline has long been employed as analytical and separating agents due to its universal chelating ability offered by the heterocyclic N and phenolate O atoms and fiuorescent property possessed by the conjugate system. In order to increase its fluorescence capability and conjugate system, 3-thiophene has been added. A novel 8-hydroxyquinoline derivative ligand containing thiophene group ( E )-2-[ 2-( 3-thiophenyl ) ethenyl]-8-hydroxyquinoline(4) and its corresponding zinc complex(5) were synthesized and identified via 1 H NMR, FTIR, UV-Vis, X-ray structural analysis and elemental analyses. The crystal structures of interme-diate (E)-2-[2-(3-thiophenyl) ethenyl]-8-acetoxyquinoline(3) and ligand 4 were characterized by single-crystal X-ray diffraction. X-Ray structural analysis showed that there was no obvious hydrogen-bonding interac-tion between the molecules of compound 3 . The crystal reticular structure of compound 4 was constructed as a result of intermolecular O-H…S hydrogen bonds. The aggregation behaviors of zinc salts and compound 4 in solutions were investigated with a variety of techniques, including 1 H NMR, UV-Vis and fluorescence. The fluorescence lifetime of complex 5 was determined in the solid state and its τ value is 18.8 ms. Organic light-emitting diodes built using complex 5 emitted yellow light, in which the 1,3,5-tris(1-phenyl-1H-benzimidazol-2-yl)benzene(TPBi) acts as the electronic transmission layer, while N,N’-bis-(1-naphthalenyl)-N,N’-bis-phenyl-(1,1’-biphenyl)-4,4’-diamine(NPB) acts as hole transport material.关键词
