本論文主要分為兩大部分，第一部分是介紹以phenanthroimidazole與carbarzole基團所形成的兩種新型藍光材料(PBC及PBnC)。phenanthroimidazole是一個高效率籃紫光材料，並作為深藍光發光體的核心結構。我們利用PBC材料當作放光層製作成有機發光元件，元件為深藍色放光(CIEy < 0.06)，外部量子效率達6.6%。經由時間解析電激發光譜系統量測，觀察到元件具有三重態-三重態緩解效應所貢獻的延遲螢光。
第二部分我們研究利用單一放光層以非摻雜的方式製作白光有機發光二極體(WOLED)，Cz9Phan分子為深藍色放光(451 nm)，分子經由堆疊後會產生excimer效應而放出綠光(540 nm)，因此形成白光。利用Cz9Phan當作放光層製作成有機發光元件，元件亮度1000 nit時，最大外部量子效率為3.6%，驅動電壓為4.2 V，CIE色座標位於(0.30,0.33)。這種以非摻雜的方式製作WOLED能有效的降低製程的複雜性，對於現代白光OLED顯示及照明技術更有成本效益的優勢。

In first part of the thesis, we describe two novel blue emission materials based on phenanthroimidazole/carbarzole (PBC and PBnC). Phenanthroimidazole is a highly efficient violet-blue chromophore and used as core structures for deep blue emitter. OLEDs using PBC as emitting layer with an EQE of 6.6% and deep blue emission (CIEy < 0.06). By using transient electroluminescence measurements, the devices observed significant delayed fluorescence via triplet–triplet annihilation. The additional effect of extra singlet excitons form the basis for the improved EQE of 6.6% observed for the device.
In the second part, we study pragmatic white organic light emitting diodes (WOLED) incorporating a single organic component only. The dual, far separated monomer (451 nm) and excimer (540 nm) of Cz9PhAn make feasible the white light generation. Exploiting Cz9PhAn as the single emitter, a white organic light emitting diode (WOLED) was fabricated with a maximum external quantum efficiency of 3.6% at 1000 cd m-2 (4.2 V) with Commission Internationale de l’Eclairage (CIE) coordinates of (0.30, 0.33). This non-doped, single component WOLED significantly reduces the complexity of the fabrication process and hence renders a green and cost-effective alternative among the contemporary display/lighting technologies.
