摘要

第一部份，芘類分子有相當好的光電性質，僅有非常少數的文獻被報導用於OLED的材料上，因此我們經由簡單的修飾與多芳香胺類的結合創造出一些具高發光性質的芘衍生化合物，也應用於OLED的元件上，最終在綠色的摻雜元件上得到非常好的效果，可作為往後類似物發展的依據。
第二部分，我們利用圓型偏極材料BINOL衍生分子進行偏極化OLED元件的開發，進行簡單的蒸鍍元件製作後發現並不能製作出偏極化的元件，後引入了摩擦配向製程可以進一步的發展出俱線性偏極光的發光膜，而偏光比並不夠好。
第三部分，在有機薄膜電晶體材料中，以線狀型多苯環分子的研究最為卓越，線狀型多芳香環碳氫化合物更是目前最有發展潛力的，一直都受到科學家的重視，但由於合成上的限制，以致於分子骨架並非很多樣性。我們利用實驗室開發的催化劑或文獻中發現的ICl環化試劑進行線狀型多芳香環碳氫化合物的開發，並進行性質的研究找尋其合適的應用性，後並設法改良使其成為更具優異性質的衍生物與發展出由線型轉變成盤狀的多苯環化合物。

Chapter I
　　Pyrene, a flat aromatic molecule, exhibits excellent fluorescent properties. Recently these studies have few reported on OLEDs. Herein We develop highly fluorescent pyrene series that combined with polyamines by easily synthesized. Finally excellent green doped and blue OLEDs devices were fabricated and explored the efficient approach to modify flat aromatic molecule like this.
Chapter II
We design and synthesize a series of BINOL chiral (Circular polarized) materials for the application in polarized EL. The devices were fabricated by regular thermal deposition show ‘NO’ polarized properties. Next We lead into rubbing alignment process liked LC (liquid crystal) to fabricate devices that show polarized properties. Polarized ratio is about 4.0, but it is not good enough.
Furthermore, we also used highly self-assemble Discotic LCs to make several polarized test and with a excellent polarized ratio is about 20. Finally, because of material’s energy level not match and the limit of process we can’t fabricate a fully polarized device.
Chapter III

　　Rod-type polycyclic aromatic hydrocarbons (PAHs) attracted many scientists because it exhibit specific optical property can be applied in the research of OTFT. However, it was difficult to achieve the synthesis of these shape materials exhibit variety of these had been studied. Herein, we used ICl to cyclization internal alkynes or TpRuPPh3(CH3CN)2SbF6 to catalyze terminal alkynes to achieve rod-type PAHs and characterized. We also modified it to become the much suitable for OTFT and tried to derivative plane-type PAHs from rod-types.
