| 中文摘要 | a series of new ppv oligomers containing 8-substituted quinoline, 2,2'-(arylenedivinylene) bis-8-quinoline derivatives, were designed and synthesized via a knoevenagel condensation reaction of quinaldine, 8-hydroxy-or 8-methoxy-quinaldine with aromatic dialdehydes. these ppv oligomers were characterized by h-1 and c-13-nmr, x-ray diffraction, elemental analysis, uv-visible and fluorescence spectroscopies. the x-ray diffraction investigation showed that there are intermolecular pi...pi interactions in the solid state in 1 and 3. the optical and photoluminescent properties study demonstrated that the emission color of the resulting materials varies from blue to yellow and is dependent on the substituents (pi-donor and pi-acceptor groups) on both sides of the conjugated molecules and the aromatic core in the middle of the conjugated backbones. the electroluminescent devices using compounds 1-4 as the emitters and electron-transporting layers were fabricated with the structure ito/npb/emitter/lif/al. the best device performance with the maximum brightness of 5530 cd m(-2) and the luminous efficiency of 2.4 cd a(-1) is achieved by using compound 4, with intramolecular charge transfer character, as the emitter; these values represent a more than 5-fold improvement in brightness and efficiency compared to compound 3 without methoxy groups on the phenyl rings. |
