成功地合成了柔性脂肪链段和刚性发光链段相互交替的共聚物,并对其进行了表征.发现该聚合物的荧光随柔性链段的增长而增强的实验结果.用所合成的共聚物作发光层,研制出了发光亮度可达190cd/m~2,最小开启电压为15V的发蓝色光的聚合物发光二极管及平板显示屏.讨论了(口恶)二唑衍生物(PBD)和8-羟基喹淋铝(Alq_3)电子输运层的引入对器件的发光亮度和稳定性的影响.
The copolymer of flexible aliphatic segments and rigid luminescent segments alternating with each other was successfully synthesized and characterized, and the experimental results that the fluorescence of the polymer is enhanced with the increase of flexible segments have been obtained. As a light emitting layer, a blue light emitting polymer light emitting diode and a flat panel display with a luminance of 190 cd / m 2 and a minimum turn on voltage of 15 V were developed. The oxadiazole derivatives (PBD) and Effect of the introduction of 8-hydroxyquinale (Alq_3) electron transport layer on the luminescence brightness and stability of the devices.
