dc.description.abstract | 本篇論文合成了以蒽為核心的噁二唑衍生物1、2及苯并咪唑衍生物3,希望藉由噁二唑及苯并咪唑良好的電子傳輸能力提高分子在OLED元件中的表現,最終達到提高OLED效率的目的。
而從低溫磷光光譜與低溫螢光光譜的重疊可以間接證實我們所合成出來的化合物具有三重態-三重態湮滅上轉換的特性,更進一步,透過引入敏料,成功地使化合物1-3在溶液態中的放光藍移,直接地觀察到TTA-UC的現象 OLED元件在目前嘗試的最佳架構下,化合物3的最大亮度8364 cd/m2,最大電流效率8.84 cd/A,最大功率效率5.74 lm/W,最大外部量子效率6.35%,距離商業應用之TTA-UC材料標準之7-8%相當接近,且從TrEL圖中可以看見延遲螢光現象較不明顯,在對於反應速度要求十分嚴苛之動態顯示器上應用具有優勢,是具有專利保護與生產價值之有機發光材料。 | zh_TW |
dc.description.abstract | We have synthesized oxadiazole derivatives 1 and 2 and benzimidazole derivatives 3 of anthracene. By introducing these functional groups, it could enhance the electron mobility of anthracene, resulting in better performance of OLED device.
The overlap of low temperature fluorescence spectrum and low temperature phosphorescence spectrum indirectly indicated that TTA-UC had occurred. By introducing sensitizer, we could observe the process of TTA-UC directly. Compound 3 in a non-doped device exhibits a maximum luminance of 8364 cd/m2, maximum current efficiency of 8.84 cd/A, maximum power efficiency of 5.74 lm/W, and maximum external quantum efficiency (EQE) of 6.35%, which is not far from commercial application(7-8%). And its transient electroluminescence (TrEL) diagram were shown no obvious delayed fluorescence, which made it more advantage in application of dynamic display. | en |
