In this thesis, we tried to prepare such nanocomposites using fluorescent surfactants as templates. In the first part, fluorescent surfactants with different hydrophobic chain length were successfully synthesized by multiple coupling reactions. After Sol-Gel process, mesostructured nanocomposites with optoelectronic properties were obtained in either powder form or as thin films by one-step synthesis. Photoluminescence (PL) behavior and physical properties of the resulting materials were fully characterized by several techniques. In the second part, fluorescent surfactants with different conjugated system were synthesized and then used as templates to prepare functional nanocomposites. The resulting nanocomposites could have both the ordered mesostructure and the PL property without further treatments. In short, we successfully prepared mesostructured nanocomposites with optoelectronic property by one-step synthesis in both parts. In the third part, we tried to develop a method which could prepare nanocrystalline organics/TiO2 porous composites in one step. The physical properties of the composites were characterized by the N2 adsorption-desorption isotherm, XRD, UV-Vis, PL, TGA, TEM, and SEM.謝誌..............................Ⅰ 摘要..............................Ⅱ 摘要(英文)........................Ⅲ 目錄..............................Ⅳ 圖目錄............................Ⅷ 表目錄............................ⅩⅢ 第一章 緒論 1-1 中孔洞材料簡介.............................1 1-2 界面活性劑性質.............................4 1-2.1 界面活性劑結構及分類........................4 1-2.2 微胞概念....................................6 1-3 中孔洞材料應用..................................7 1-3.1 非均相催化反應..............................7 1-3.2 藥物傳遞釋放................................7 1-3.3 生物標定....................................8 1-4 有機無機複合材料................................8 1-4.1 共縮合(co-condensation)法...................9 1-4.2 後修飾法....................................11 1-4.2 共縮合 / 聚合反應...........................12 1-5 金屬氧化物的中孔材料............................13 1-6 本論文研究方向..................................16 第二章 不同疏水端長度的螢光型界面活性劑應用在孔洞材料上的性 質探討 2-1 簡介............................................17 2-1.1 實驗架構....................................17 2-2 界面活性劑合成..................................18 2-3 中孔洞粉末材料的合成、鑑定及其性質探討..........21 2-3.1 中孔洞粉末的合成............................21 2-3.2 中孔洞粉末的鑑定............................21 2-3.3 中孔洞粉末的性質探討........................22 2-4 中孔洞薄膜的製備、鑑定及其性質探討..............36 2-4.1 中孔洞薄膜的製備............................36 2-4.2 中孔洞薄膜的鑑定............................36 2-4.3 中孔洞薄膜的性質探討........................37 2-5 共混合界面活性劑的中孔洞薄膜之光學性質..........46 2-5.1 目的........................................46 2-5.2 實驗材料及方法簡述..........................46 2-5.3 共混合界面活性劑的中孔洞薄膜之鑑定..........48 2-6 簡結............................................52 第三章 含不同共軛長度發光團的螢光型界面活性劑應用在孔洞材料 上的性質探討 3-1 實驗架構........................................54 3-2 界面活性劑合成..................................55 3-3 中孔洞粉末材料的合成、鑑定及其性質探討..........59 3-3.1 中孔洞粉末材料的合成與鑑定..................59 3-3.2中孔洞材料的性質探討.........................59 3-4 中孔洞薄膜的製備、鑑定及其性質探討..............73 3-4.1 中孔洞薄膜的製備............................73 3-4.2 中孔洞薄膜的性質探討........................73 3-5 簡結............................................79 第四章 合成具有結晶性之二氧化鈦孔洞材料 4-1 簡介及實驗架構..................................81 4-2 孔洞性二氧化鈦粉末的合成、鑑定及其性質探討......81 4-2.1 孔洞性二氧化鈦粉末的合成....................81 4-2.2 孔洞性二氧化鈦粉末的鑑定....................82 4-2.3 孔洞性二氧化鈦粉末的性質探討................83 4-3 簡結............................................94 第五章 結論.........................................95 第六章 實驗部分 6-1 儀器............................................98 6-2 溶劑純化........................................102 6-3 實驗過程........................................102 6-4 實驗步驟 (有機合成) 第二章............................................103 第三章............................................115 6-5 實驗步驟 (中孔洞材料) 6-5.1 中孔粉末合成................................123 6-5.2 中孔薄膜製備................................123 6-5.3 共混合界面活性劑的中孔薄膜製備..............124 6-5.4 孔洞性二氧化鈦粉末的合成....................124 6-5.5 萃取步驟....................................125 參考文獻............................................1267298278 bytesapplication/pdfen-US複合材料中孔洞螢光界面活性劑nanocompositesmesoporousfluorescent surfactants螢光界面活性劑的合成及其在孔洞材料上的應用Synthesis of fluorescent surfactants and their applications in porous materialsthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/51820/1/ntu-94-R92223013-1.pdf
