中文摘要
溶液製程的有機高分子電激發光元件 (Polymer light-emitting diodes；PLED) 具有發展潛力，其優點為：低成本、高對比度、大面積製程、自發光特性……等。文獻指出紅光與綠光材料在現今效率、色純度與壽命都高於藍光，白光通常由三原色紅、藍與綠光或互補色混光而成 (例:水藍+紅色，深藍+橘色)，因此藍光材料扮演重要的角色。
常見的藍光材料為Polyfluorene (PF)的衍生物poly[9,9-dioctylfluorenyl-2,7- diyl)-co-(4,4'-N-4-s-butylphenyl))diphenylamine)] (PFO-DMP)，其特性為其具高發光效率、熱穩定性高與合成容易，但是PF衍生物的缺點為製作成元件時，易隨增加電壓而產生紅位移現象，並造成效率大幅下降，本論文針對此現象進行改良，研究的架構如下：
1. 將PFO–DMP製作成藍光標準元件。
2. 引用本實驗室所合成出來的spirobifluorene衍生物SFPY50-S取代PFO–DMP，應用於深藍光電激發光元件中，改善PFO–DMP的缺點。
首先研究市售藍光材料PFO–DMP與本實驗室自行合成的深藍光高分子材料SFPY50-S之材料特性，包含了吸收光譜、發光光譜、熱裂解溫度(Td)等材料量測，後將其作成元件結構為ITO/PEDOT：PSS/發光層(EML)/LiF/Ca/Al。將此藍光PFO–DMP元件製作成基本元件，再以深藍光SFPY50-S材料取代發光層PFO–DMP，將元件優化後製作成深藍光CIE(0.16 , 0.17)且色穩定度高的高分子電激發光元件(PLED)。


關鍵字：深藍光高分子、PFO-DMP、紅位移、色穩定度

Abstract
Solution-process polymer light-emitting diodes (PLEDs) exhibiting low-cost, high-contrast, large area process, self-properties and so on, therefore, Solution-process PLEDs occupy an important position. Literature indicates that red and green light which its efficiency, color purity and life time was higher than Blue light in today. White light usually consist of three primary colors, red, blue and green light or complementary light mix together (ex: water blue + red, blue + orange), Blue light materials play an important role.
Common Blu-ray materials Polyfluorene (PF) derivatives of poly[9,9-dioctylfluorenyl-2,7-diyl)-co-(4,4'-N-4-s-butylphenyl)) diphenylamine)] (PFO-DMP), whose characteristics are its high efficiency, high thermal stability and composition easy, but its disadvantages are PF derivatives for the production of components red shift with increased voltage and resulting efficiency dropped, so this thesis for improvement of this disadvantage, our research framework is as follows :
1. Use PFO – DMP as Blue Ray standard components.
2. Use our laboratory synthesis of spirobifluorene derivatives SFPY50-S replace PFO – DMP and then make Blue Ray standard components.
First research two polymer blue light materials one is commercially PFO-DMP and another is our laboratory's deep blue light SFPY50-S, including absorption and luminescence spectra, thermal decomposition temperature (Td), after that our component structure as the ITO/PEDOT:PSS/Emitting layer (EML)/LiF/Ca/Al. Use PFO – DMP as blue light elemental components, after replaced blue light emitting layer PFO – DMP by SFPY50-S, we will optimized into CIE blue light (0.16, 0.17) and high color stability of deep blue polymer light-emitting diodes (PLED).
