本論文研究一系列新開發之三氮唑吡啶(triazolopyridine)之衍生物(TRP-01、TRP-02、TRP-03和TRP-04)，藉由傳遞電洞特性良好的三苯胺(triphenylamine)分子或咔唑(carbazole)分子共軛具有傳遞電子特性的三氮唑吡啶基團，合成雙極性材料應用於磷光元件之主發光體，此系列材料三重態能隙大約為2.5 eV，因此選擇摻雜三重態能隙為2.34 eV的Ir(ppy)3作為發光客體，使激子被侷限於發光層中有效地複合、放光。在第四章中，第一部分討論客體摻雜濃度在TRP系列元件中的影響；第二部分討論不同的主體材料之最佳化元件特性，以TRP-02元件特性表現最優異，驅動電壓2.6 V、功率效率69.7 lm/W、電流效率62.5 cd/A，以及外部量子效率16.7 %，實驗結果證實三氮唑吡啶之衍生物適合應用於綠光元件之主體材料。

In this thesis, we developed and analyzed the PhOLED based on triazolopyridine derivatives, TRP-01、TRP-02、TRP-03 and TRP-04. The triplet energy of TRP series was about 2.5 eV, so green PhOLEDs were developed by using the TRP series as the host of green emitter fac-tris(2-phenylpyridinato-N, C2’) iridium (III) [Ir(ppy)3] with triplet energy gap about 2.34 eV.
In the fourth chapter, the effect of concentration of guest material on device performance was discussed first. The optimization parameters of devices was then discussed. TRP-02 shows the best device performance with turn on voltage of 2.6 V, power efficiency of 69.7 lm/W, current efficiency of 62.5 cd/A, and external quantum efficiency of 16.7 %. The experimental results disclosed the suitability of the triazolopyridine derivatives for green phosphorescent devices.
