摘要

第一部分:利用連續的Suzuki偶合反應，LDA環化反應， Friedel-Crafts脫水反應，我們成功地建立一系列具不同共軛長度和不同吡啶環數目之新穎含茚吡啶共軛寡聚物分子的合成方法。實驗結果顯示，藉由在主共軛鏈引入多電子吡啶環，可有效調控分子之光物理、熱穩定和電化學等性質。其中，T2N發現可以當作一紫外光放光元件材料，同時可運用為紅色摻混染料的主體材料，在元件的效能上有不錯的表現。

第二部份:我們成功的利用click chemistry及Suzuki偶合反應，分別開發一系列4-aryl-1,2,3-triazole及2-aryl-pyrimidine衍生物之新穎配位基。與銥金屬反應後可以得到相對應的磷光發光材料。實驗結果顯示，利用不同的取代基，可以調控出不同的光色，其中N-Firpic製作成發光元件後亦有不錯的效率。

Abstract
This thesis divide into 2 part:
The first part, we have successfully synthesized a series of indenopyridine -embedded oligomers, by using of selectively Suzuki coupling reaction, LDA cyclization reaction, Feiedel-Crafts alkylation. The promising optoelectronic properties, thermal stabilites of these materials and the UV-OLED of T2N were demonstrated. T2N can be also used as the host material for red and green phosphorescent dopants, the experimental results show very high external quantum efficiencies in the phosphorescent OLED.
The second part, we have synthesized two novel series of triplet emitters, based on aryl-1,2,3-triazole and aryl-pyrimidine systems, the aryl-1,2,3-triazole ligand was synthesized via Sonogashira coupling reaction, click chemistry reaction. The aryl -pyrimidine ligand was synthesized via Suzuki coupling reaction. These ligands further react with IrCl3 to give corresponding triplet emitters. the experimental result shows, N-Firpic is a very good material in the phosphorescent OLED.
