摘　　要：合成了一种深红色发光的聚苯乙烯喹啉(PPV-Q)材料,研究了其光致发光,电致发光及吸收光谱。这种材料在紫外和蓝光区具有很强的吸收能力,波长为463 nm的光对此材料具有最高的激发能力。用此材料作为发光层制备了ITO/PPV-Q/Al结构的电致发光器件,发光光谱的中心波长为670 nm,发光光谱的半高全宽为90 nm左右。在不同驱动电压下,器件电致发光的色坐标(x=0.67,y=0.32)基本上没有变化,是一种深红色的电致发光。器件中的电流随驱动电压的增加而明显增强,导致器件稳定性的降低。A deep red emission polymer （PPV-Q） was synthesized successfully. The photolumineseence, eleetroluminescence and absorption performance of this polymer were studied in detail. The experimental results show that the polymer has strong absorption in the ultraviolet and blue emission wavelength region The effective excitation wavelength is about 463nm. The organic emitting diodes based on the polymer as the active layer were prepared with the device structure： ITO/PPV-Q/AI. The electrolumineseence of these devices was obtained and the peak emission wavelength is about 670 nm. the electroluminescence spectra have the full width at half maximum of about 90 nm. The CIE coordinate remains constant at （x=0.67, y=0. 32） with- out change with the increase in driving voltage. The electroluminescence of this device （ITO/PPV-Q/A1） shows deep red emission. However, the current increases with the increase in driving voltage.
