dc.description.abstract類沸石咪唑骨架材料是屬於金屬有機骨架材料的範疇,其主要是利用咪唑或是咪唑衍生 物(Im)當作有機配位體與鋅、鈷等過渡金屬(M)鍵結所形成的聚合物,結構中Im-M-Im的 鍵結角度約為145度,與天然沸石中Si-O-Si的鍵結角度大約相同,故被稱之為類沸石咪 唑骨架材料,目前主要有儲存氣體、分離混和氣體、非均相催化和藥物載體的應用。本 論文所介紹的類沸石咪唑骨架材料-90(Zeolitic Imidazolate Framework-90;ZIF-90) 已有報導指出此材料易於官能基化的特點,並具有極為優異的水熱穩定性。然而,目前 合成ZIF-90之方法大多需使用有機溶劑(如DMF),但若大量製造ZIF-90時,所產生的廢 液將對於環境造成負擔。為了符合綠色化學之製程,此研究中,我們提供了一種於水相 系統中製備ZIF-90之方法,能夠製造出粒徑大小一致且尺寸具有均一性的ZIF-90。zh_TW
dc.description.abstractIn zeolitic imidazolate frameworks (ZIFs), a subclass of metal–organic frameworks (MOFs), metal ions such as Zn2+ and Co2+ are linked through the nitrogen atoms of the deprotonated imidazolate to form neutral frameworks and provide a tunable crystalline structure and porosity and a high internal surface area. Additionally, the M–Im–M angle is similar to that of the Si–O–Si angle (145o) preferred in zeolites. This fact has led to the synthesis of a large number of ZIFs with zeolite-type tetrahedral topologies. Therefore, ZIFs have recently attracted considerable attention for applications in gas storage, separation of small molecules, heterogeneous catalysis, sensors and drug delivery. Zeolitic Imidazolate Framework-90 (ZIF-90), the main character of the thesis, was reported to have high thermal and solvent stability. However, most of the strategies reported so far on the synthesis of ZIF-90 have involved the use of solvents, such as dimethyl formamide (DMF), methanol, or other organic solvents which are also expensive, in addition to their environmental concerns, such as toxicity, high-pollution, and waste treatment issues. Herein, we report for the first time, a rapid and eco-friendly strategy for the synthesis of ZIF-90 under aqueous conditions, and thus, ZIF-90 having uniform particle sizes can be produced.en_US
