中文摘要
本論文研究HJJ系列材料的光物理特性及其於有機發光二極體的元件應用,此系列材料的合成理念是以兩苯環平行相對的二聚對二甲苯([2,2]-paracyclophane)分子作為中心,在二聚對二甲苯的兩個苯環分別接上不同的基團作為電子供體與電子受體。
本論文藉由量測並分析各材料的光物理特性,選擇搭配適合的傳輸材料進行螢光及磷光元件的製作,探討材料與元件表現之間的關係。
在螢光元件的應用上,HJJ-2螢光元件在外部量子效率、電流效率與功率效率的表現上分別是1.8%、1.6 cd/A、1.4 lm/W; 以HJJ-5作為主體的螢光元件在外部量子效率、電流效率與功率效率的表現上分別為0.06%、0.1 cd/A、0.09 lm/W;HJJ-6螢光元件在外部量子效率、電流效率與功率效率的表現上分別為0.35%、0.3 cd/A、0.32 lm/W。以HJJ-5作為磷光主體的元件外部量子效率、電流效率與功率效率則為1.6%、4.2 cd/A、3.3 lm/W。
Abstract
In this thesis, we studied the HJJ series of synthetic materials, and measured the photophysical properties and the applications on organic light-emitting devices. The synthetic concepts of these materials were centered on the paracyclophane molecule which its two benzene rings were parallel, and the two benzene rinds were connected to different groups as Donor and Acceptor..
In this paper, by measuring and analyzing the photophysical properties of each material, we chose the appropriate transporting materials to process fluorescent and phosphorescent devices, and explored the relationship between materials and devices performance.
After optimization, HJJ-2 fluorescence device showed 1.8%, 1.6 cd/A, and 1.4 lm/W in EQE, current efficiency, and power efficiency;fluorescence device which used HJJ-5 as host material showed 0.06%、0.1 cd/A、0.09 lm/W in EQE, current efficiency, and power efficiency;HJJ-6 fluorescence device showed 0.35%、0.3 cd/A、0.32 lm/W in EQE, current efficiency, and power efficiency;phosphorescence device which used HJJ-5 as host material showed 1.6%、4.2 cd/A、3.3 lm/W in EQE, current efficiency, and power efficiency.
