Abstract:	本論文設計合成一系列以笏(fluorene)衍生物做為主體的有機發光二極體材料，利用在9,9¢-位置接上苯環成咔哚(cardo)或9,9¢-位置接上另一笏取代，形成螺旋雙笏(spirobifluorene)結構，且藉由中心元素 9 位置碳、矽元素的不同，了解結構上碳和矽元素的差異對光電特性的影響，並以熱重量分析儀(TGA)及微差熱掃描卡計(DSC)量測化合物熱性質；紫外/可見光光譜儀、螢光光譜儀、光電子光譜儀、積分球了解化合物的光物理性質。最後，其中碳、矽兩組的四個化合物做成元件，探討其元件效率及亮度等電激發光性質。 The present thesis designed and synthesized a series of fluorene-based materials for organic light-emitting diodes (OLEDs). Particulaly, 9,9-diphenyl-substituted fluorene (cardo), 9,9-spirobifluorene, and their silicon derivatives (silacardo and spirosilabifluorene) bearing electronic donor-acceptor substituent on 2 and 7 position are characterized for photoelectronic characteristics. The influence of the difference from the central carbon and silicon elements were investigated by thermogravimetric analyzer, differential scanning calorimeter, UV/Visible spectrophotometer, fluorescence spectrophotometer, photoelectron spectrometer, integrating-sphere for solid-state fluorescence quantum yield, and OLEDs.
