Abstract:	自從Adachi教授提出了第三代有機發光二極體材料—熱活化延遲螢光材料的概念後，這幾年相關的研究與發表的論文以倍數成長，大家積極尋找這個成本低且具有高電激發光效率又穩定的材料。本論文設計一系列的化合物，採用二均三甲苯硼做為電子受體結構，與不同的電子予體結構，如9,9-二甲基-9,10-二氫吖啶與咔唑等衍生物搭配，並分成沒有苯硼從氮延伸(硼氮系列)與非從氮延伸(硼碳系列)兩個部分進行討論，根據量測的化學與物理特性整理歸納兩個系列結構設計的優缺點。除此之外，我們將化合物做成非摻混型的有機發光二極體元件，分析討論硼化合物有機發光二極體的表現。其中以化合物BPhDMAC可以達到最小的ΔEST值及最高外部量子效率，是標準的熱活化延遲螢光材料。;Since professor Adachi proposed the concept of 3rd generation OLED – thermally activated delayed fluorescence(TADF), the numbers of published papers about TADF have rapidly grown in recent years. Researchers vigorously find and develop a new low cost, high efficiency, and stable TADF OLED material. In this research, we design a series of compounds by using dimesitylarylborane as the acceptor, and coupling with different donors. We divide into two parts to discuss, one is B-C series and the other is B-N series. The photophysical and electrochemical properties of these new compounds were analyzed to determine which series is better designed for TADF. More over, we fabricated non-doped devices to observe the performance of these devices. The results showed that the BPhDMAC gave the smallest ΔEST and the most excellent EQE. It exhibited TADF characteristics.
