dc.description.abstract | 本實驗目的在於合成良好的電洞注入及傳輸材料以取代目前使用最為廣泛的PEDOT:PSS,並將此系列的高分子材料運用在有機電激發光元件中,試驗其作為電洞注入層及電洞傳輸層的性質並加以探討。合成出的高分子材料是將具有剛硬結構的芴和具有電洞傳輸性質的三苯基胺衍生物依不同比例以異佛爾酮二異氰酸酯連接成聚氨酯型態的五種共聚合物。聚氨酯本身結構即具有良好的電洞傳輸效果,本實驗目的在這系統中找出最佳比例條件的聚合物能運用在電激發光元件中讓元件發光效率及亮度有效提升。元件製備的部份分為兩個系列:
一、ITO/PEDOT:PSS/PU/Ir(ppy)3+t-PBD+PVK/Mg/Ag 單獨使用合成之聚氨酯為電洞注入及傳輸層並測量其發光性質,和標準元件S1:ITO/Ir(ppy)3+t-PBD+PVK/Mg/Ag之發光性質比較,相較於S1,亮度可從5190 cd/m2有效提升至10030 cd/m2。效率也由17.2 cd/A提升至27.9 cd/A,顯示本實驗合成之聚氨酯材料用於電洞注入及傳輸層對元件發光亮度及效率有顯著提升。 二、ITO/PEDOT:PSS/PU+2.5 wt%P2M /Ir(ppy)3+t-PBD+PVK/Mg/Ag 此系列元件將合成之聚氨酯作為電洞傳輸層中引入P2M,將這一系列元件和標準元件S1:ITO/PEDOT:PSS/Ir(ppy)3+t-PBD+PVK/Mg/Ag 發光性質比較。在此系列中,相較於標準元件S1,亮度可由 5190 cd/m2有效 提升至8560 cd/m2。效率也由17.2 cd/A提升至18 cd/A,顯示本實驗合 成的電洞傳輸材料在加入具有磷酸官能性之壓克力材料P2M對於提升元件效能有極大助益。 | zh_TW |
dc.description.abstract | In this thesis, the series of hole-injecting and hole-transporting materials are synthesized and characterized. The series is TRI-IPDI-SF series, triarylamine derivatives (denoted as TRI) and Spiro-fluorene derivatives (denoted as SF) linked by isophorone diisocyanate with different ratios to form a series of polyurehtanes (PU). These materials are applied in electroluminescent device as hole-injecting and hole-transporting layer to improve the performance. The devices are separated into two systems:
a. ITO/PEDOT:PSS/PU/Ir(ppy)3+t-PBD+PVK/Mg/Ag : PUs were applied in the devices and the devices were compared with the standard device S1:ITO/ PEDOT:PSS/Ir(ppy)3+t-PBD+PVK/Mg/Ag. The brightness was increased to 10030 cd/m2, the current efficiency rose to 27.9 cd/A and turn-on voltage was 12V (at 100 cd/m2), compared to 5190 cd/m2, 17.2 cd/A and 12.5 V in S1; and b. ITO/PEDOT:PSS/PU+2.5 wt%P2M/Ir(ppy)3+t-PBD+PVK/Mg/Ag, compared to standard device S1: ITO/PEDOT:PSS/ Ir(ppy)3+t-PBD+PVK/Mg/Ag. The brightness of copolymer was increased to 8560 cd/m2, the current efficiency was up to 18 cd/A, compared to 5190 cd/m2 and 17.2 cd/A in S1. | en |
