摘要

在本篇論文中，透過共縮合的方式合成出含染料的奈米孔洞材料，此實驗合成出的含染料奈米孔洞材料，由於高表面積孔洞具親水性，溶液容易擴散進入孔洞接觸表面鍵結染料。透過化學鍵結的方式鍵結染料在孔洞材料的孔壁表面及孔壁內部，此固態奈米孔洞染料可重複使用，改善了傳統染料不能重複利用的缺點，同時減少藥品的浪費及降低對環境的污染，符合綠色化學的要旨。
由於此含矽奈米孔洞材料，在強鹼時易溶解，而導致染料溶解於溶液中，因此，進一步利用共縮合的方式，將長碳鏈的矽烷與染料共縮合於奈米孔洞材料，長碳鏈的矽烷則可以改善孔洞材料的耐鹼性。比較共縮合法及後修飾法合成含染料奈米孔洞材料耐鹼穩定性，共縮合法有較優越表現。

Nanoporous materials tethering dye have been successfully synthesized via the bonding between nanoporous material with different kinds of functional groups and dyes with variable functional groups. Designed bonding and characterizations of dye nanoporous material is the key issue in this study.
Silica nanoporous material is ready to dissolve in basic aqueous solution. Thus, the improvement of materials in basic solution is essential for their application. Alkyl silanes were co-condensated with materials during the synthesis process. Products with alkyl chains have much better stability in basic solution than pure silica mterials.
