| dc.description.abstract | 我們利用簡單合成，成功得到一系列含benzimidazole 或arylamine 之
衍生物，其螢光光色從紫藍到橘紅。此系列化合物具有好的熱穩定性其玻
璃轉換溫度（Tg）介於104 - 170 oC 及熱裂解溫度（Td）介於340 - 493 oC。
元件製程應用方面，（i）多層元件：以EF-II 為電子傳輸材料；Alq3 為發光
材料；NPB 為電洞傳輸材料之元件，ITO/NPB/Alq3/EF-II/LiF/Al，其發光效
率為： ext 1.9%；3.2 lm/W；5.9 cd/A at 100 mA/cm2。（ii）以ITO/NPB/cpd/LiF/
Al 之雙層元件結構，化合物為電子兼發光材料，有不錯的元件效率。（iii）
單層元件：含benzimidazole 與arylamine 之化合物，有良好的電子、電洞傳
輸速率（~10-5 cm2/(V·s)），製成單層元件ITO/cpd/LiF/ Al（cpd＝EF-I-N、
EF-I-N2、SPY-I-N）展現很好的發光效率及純藍至藍綠的光色，其中EF-I-N
元件效率及CIE 座標如下： ext 3.5%; 1.8 lm/W; 3.6 cd/A at 100 mA/cm2，CIE
（0.14, 0.12）。（iv）單層磷光元件：以雙極化分子化合物SPY-I-N 為主發光
體，叄雜黃色磷光材料Ir(fbi)2(acac)，其元件結構可簡化製成單層元件
ITO/SPY-I-N: Ir(fbi)2(acac) 5%/LiF/Al，顯示出極優的發光效率為： ext
6.9%；4.4 lm/W；20 cd/A at 100 mA/cm2，此效率與傳統多層磷光元件相近，
故利用此雙極化分子（ambipolar）可簡化傳統製成，具極大的應用價值。 | zh_TW |
| dc.description.abstract | In this study, we have sucessfully synthesized a series of compound
containing benzimidazole and/or arylamine moieties. These compounds emit
from purple- blue to orange-red. These compounds are amorphous with glass
transition temperatures ranging from 104 to 170 oC and high thermal
decomposition temperature (Td > 340 oC) . Among them, EF-I-N, EF-I-N2,
SPY-I-N exhibited both good electron- and hole-transporting (mobilities ~10-5
cm2/(V·s)) and emitting abilities. The single-layer devices (ITO/cpd/LiF/Al) of
them showed good performance( ext 3.5%; 1.8 lm/W; 3.6 cd/A at 100 mA/cm2
for EF-I-N based device). In addition, bi-layer electroluminescent devices of
good performance ( ext 4.2%；3.1 lm/W；4.4 cd/A at 100 mA/cm2 for EF-I-N
based device) have also been achieved using these materials as the
electron-transporting and emitting layer. Compound EF-II can be used as
electron-transporting layer. The device using Alq3 as the emitting layer and NPB
as the hole-transporting layer, ITO/NPB/Alq3/EF-II/LiF/Al, exhibited good
performance: ext 1.9%; 3.2 lm/W; 5.9 cd/A at 100 mA/cm2.
Moreover, SPY-I-N can serve as a good host for phosphorescent materials.
The single-layer device, ITO/SPY-I-N:Ir(fbi)2(acac) 5% (80 nm)/LiF/Al, usingIr(fbi)2(acac) as emissive dopant exhibited high efficiency: ext 6.9%；4.4
lm/W；20 cd/A at 100 mA/cm2. | en_US |
