離子液體結構為有機陽離子與有機或無機陰離子所組成之離子化合物，其在寬廣 的溫度範圍內處於液體狀態，並具有高熱穩定、無發揮性、不易燃等特性，可降低使 用揮發性有機溶劑對環境的汙染，因此離子液體被稱為是一種綠色溶劑。本研究計畫 以離子液體所具有的特性為基礎，進行磁性離子液體的合成與其物、化性質研究，以 兩年為期，逐年探討： 1.磁性離子液體合成與其物性研究。 2.磁性離子液體的化性研究。 磁性離子液體是指在外加磁場的作用下，具有一定磁響應能力的離子液體。近年 來以磁性離子液體為溶劑或催化劑，在合成反應上通過外加磁場調控，可以獲得不同 奈米結構的材料、以及再回收與使用離子液體。不過目前磁性離子液體的研究上，大 多集中在[BMIM][FeCl4]離子液體，結構變化不多。由於離子液體中陰、陽離子的改變 都可能對其物、化性質產生重大的影響，因此本研究計畫以實驗室已建立的離子液體 研究為基礎，合成咪唑側鏈具有芳香族結構的新穎型磁性離子液體，並探討其物、化 性質，以期建立磁性離子液體相關學理基礎並擴展其應用領域。 Ionic liquids are molten salts that are commonly composed of relatively large organic cations and inorganic or organic anions. They have excellent properties such as wide temperature operation range, high thermal stability, and non-flammability. Moreover, ionic liquids have been termed as "green solvents" as they are non-volatility that avoids the solvent losses. This research will investigate the synthesis of magnetic ionic liquid and study the physicochemical properties based on the characteristics of ionic liquids. This program will proceed as a two-year project to discuss following topics year by year. 1. Synthesis of magnetic ionic liquid and discuss the physical properties thereof. 2. Study chemical properties of the magnetic ionic liquids. Magnetic ionic liquids have a strong response to external magnetic fields. They are used to synthesize different nanostructured polymers and be recycled through external magnetic fields. Recent years, most of studies with magnetic ionic liquids are focused on 1-butyl-3- methyimidazolium tetrachloroferrate. Changing the cation or anion of ionic liquids could notable influence the physicochemical property of the materials. This research is base on the characteristics of ionic liquids and synthesis technology in our previous work. We will synthesize novel tunable aryl alkyl magnetic ionic liquids and study their physical and chemical characteristics. We hope to establish the basic principles and expand the application fields of magnetic ionic liquids.
