| 摘 要： | 通过升降温差热分析(DSC)曲线、偏光显微镜、紫外吸收光谱、电化学行为曲线以及多层器件等,研究了噁二唑衍生物小分子的电学和光学性质,发现其同时具有液晶性、电子和空穴传输性、发光性等优良性能.引进R-OXD(En)层后的多层器件在低于3 V时就能得到可见光发射,在7 V时可以得到光亮度为1000 cdm-2.此系列小分子可降低有机电致发光器件开启电压,提高发光亮度和发光效率,是一种非常具有吸引力的有机电致发光小分子. |

| Abstract: | The electrical and optical properties of the small oxadiazole(OXD)derivatives are determined by DSC, polarized optical microscope(POM), UV absorption spectrum, electrochemical measurement and manufacturing multi-layers device. Liquid crystal, electron transport, cavity-transport, luminescence and other excellent characterizations are found in these R-OXD materials. The multi-layers EL device with R-OXD layer begins to emit light at below 5 V and a luminance level of 1000 cdm-2 can be obtained at only 7 V.This series of compounds is beneficial to decrease the threshold voltage in devices and to improve luminous intensity and efficiency. It’s a kind of attractive organic electroluminescent compounds. |
