Abstract:	摘要本文利用金屬鈀的催化反應，將螺環茀-吖啶及螺環雙茀的延伸物，做有效的結合，進而合成出一系列的高分子。螺環茀-吖啶具有剛性結構，所以擁有較高的熱穩定性及較高的玻璃轉換溫度，並且它也兼具電洞傳導物質的特性。這些高分子化合物，具有非常好的溶解度，可以溶於一般的有機溶劑，像是1, 2-二氯苯、二氯甲烷、四氫呋喃、甲苯及1, 2-二甲苯等。由示差熱分析儀及熱重分析儀中發現，高分子具有傑出的熱穩定性，且其玻璃轉換溫度幾乎都高於攝氏300度。所製作出來的元件，其最佳的效能如下，藍光部份的有機發光二極體其元件格式為(Glass/ITO(120nm)/PEDOT ： PSS(65nm)/ 高分子化合物ACOXP6(60nm)/Ca(30nm)/Al(130nm))，其最高效率為0.557(%)，而其最大亮度為 977 (cd/m2)，在CIE圖上的位置(0.17,0.09)，而紅光部份的有機發光二極體其元件格式為(Glass/ITO(120nm)/PEDOT：PSS(80nm)/ 高分子化合物ACTBP5(120nm)/LiF(0.7nm)/Al(130nm))，其最高效率為1.497(%) ，而其最大亮度為4667(cd/m2) ，在CIE 圖上的位置(0.65,0.34) ，綠光部份的有機發光二極體其元件格式為(Glass/ITO(120nm)/PEDOT：PSS(50nm)/高分子化合物ACTBP6(120nm)/Ca(30nm)/Al(130nm))，其最高效率為0.849(%)，而其最大亮度為13874(cd/m2)，在CIE圖上的位置(0.37,0.58)，黃光部份的有機發光二極體其元件格式為(Glass/ITO(120nm)/PEDOT：PSS(65nm)/ 高分子化合物IrP2(60nm)/LiF(0.7nm)/Al(130nm))，其最高效率為1.153(%)，而其最大亮度為671(cd/m2)，在CIE圖上的位置(0.47，0.52). Abstract: A series of novel light-emitting copolymers derived from spiro-fluorene-acridine and spiro-bifluorene, are prepared by palladium-catalyzed Suzuki coupling reaction.Spiro-fluoreneacridine have rigid structure so copolymers show high Tg and it can also be utilized as hole-transporting material.These polymers have good solubility in common organic solvents, such as 1,2-dichlorobenzene, CH2Cl2, THF, toluene, and o-xylene.DSC and TGA studies reveal that novel polymers possess excellent thermal stability with high glass transition temperatures (Tg >300oC).Blue light-emitting device (Glass/ITO(120nm)/PEDOT：PSS(65nm)/ACOXP6(60nm)/Ca(30nm)/Al(130nm)) ， showed maximal externalquantum efficiency of 0.557% and the highest brightness of 977 cd/m2,and CIE(0.17,0.09). Red light-emitting device (Glass/ITO(120nm)/PEDOT：PSS(80nm)/ACTBP5(120nm)/LiF(0.7nm)/Al(130nm))，showed maximal external quantum efficiency of 1.497% and the highest brightness of 4667 cd/m2, and CIE(0.65,0.34). Green light-emitting device (Glass/ITO(120nm)/PEDOT：PSS(50nm)/ACTBP6(120nm)/Ca(30nm)/Al(130nm)) showed maximal external quantum efficiency of 0.849% and the highest brightness of 13874cd/m2, and CIE(0.37,0.58).Yellow light-emitting device (Glass/ITO(120nm)/PEDOT：PSS(65nm)/IrP2(60nm)/LiF(0.7nm)/Al(130nm)) showed maximal external quantum efficiency of 1.153% and the highest brightness of 671cd/m2, and CIE(0.47，0.52).
