| dc.description.abstract | 本篇論文主要是合成具有雙官能基的中孔洞材料，共分為兩個部分， 第一部分是利用 P123 (Pluronic 123) 作為模板試劑，
1,2-bis-(trimethoxylsilyl)ethane (BTME) 與 Carboxyethylsilanetriol sodium salt (CES) 為共同矽源，在酸性條件下合成具有乙基與羧酸官能基之中孔洞材料 SBA-15，之後再利用 48 % H2SO4 在高溫下裂解模板 P123，得到雙官能基化的中孔洞材料 SBA-15，而 CES 含量可達60 %，仍具有良好的結構規則度。
第二部份也是利用 P123 (Pluronic 123) 作為模板試劑，
1,4-bis(triethoxysilyl)benzene (BTEB) 與 Carboxyethylsilanetriol sodium salt (CES) 為共同矽源，在酸性條件下合成具有苯環與羧酸官能基之中孔洞材料 SBA-15，之後再利用 48 % H2SO4 在高溫下裂解模板 P123，得到雙官能基化的中孔洞材料 SBA-15，而 CES 含量可達 50 %，仍具有良好的結構規則度。
以上兩部份實驗都會利用 X-ray 粉末繞射、固態核磁共振光
譜、熱重分析儀及等溫氮氣吸脫附等儀器鑑定材料的特性，了解在不同 CES 含量比例之孔洞性質變化趨勢，且對於植入的羧酸官能基定量。

| dc.description.abstract | The thesis is divided to two parts, both studied on
bifunctionalization of mesoporous materials. In part one, carboxylic acid functionalized mesoporous ethane-silicas have been synthesized with P123 as the structure-directing agent under acidic conditions via co-condensation of 1,2-bis-(trimethoxylsilyl)ethane (BTME) and carboxyethylsilanetriol sodium salt (CES). A high degree of structural ordering is still retained up to 60 mol% CES loading (based on silicon) in the synthesis mixture, and we also have acid capacity by acid-base titration, which was 4.53 mmol/g.
In part two, well-ordered hexagonal mesoporous silica SBA-15 functionalized with carboxylic acid functional groups have been synthesized via co-condensation of 1,4-bis(triethoxysilyl)benzene (BTEB) and Carboxyethylsilanetriol sodium salt (CES) templated by P123 under acidic condition. A high degree of structural ordering is still retained up to 50 mol% CES loading (based on silicon) in the synthesis mixture.
In the thesis, the materials thus obtained were characterized by a variety of techniques including X-ray diffraction (XRD), solid state 13C and 29Si NMR spectroscopy, thermogravimetric analysis (TGA) and nitrogen
sorption measurements.
