摘要

本論文主要探討以配位基(ligand) 4,4-二苯乙烯二羧酸(4,4'-stilbenedicarboxylic acid, H2SDC); (4,4'-(1-fluorothane-1,2-diyl)dibenzoic acid, H2FDDB)一系列水熱合成的孔洞性金屬有機骨架化合物(Metal-Organic Frameworks, MOFs)，分子式分別:
[Cr3(F/OH)(H2O)2O(FDDB)3]......(1)
[Cr(OH)(FDDB)]……..…...........(2)
[Al(OH)(SDC)]…………............(3)
[Al(OH)(SDC)]…………............(4)
[Ga(OH)(SDC)]…………...........(5)
[Al(OH)(FDDB)]……….............(6)
[Al(OH)(SDC)] ….….................(7)
[Ni2(SDC)2(DABCO)].................(8)
在化合物的鑑定上，以粉末X-ray繞射儀來鑑定結構外，再以SEM觀察粉末顆粒晶型與大小，並利用改變合成條件或加入長鏈胺類增加化合物結晶性，此外，以紫外-可見光光譜、固態核磁共振，熱重分析、變溫PXRD等，來探討化合物特性 ; 以及利用不同活化方式改善材料孔洞特性，並測量其低壓與高壓氣體吸附，探討各化合物的氣體儲存，來測量各化合物在氣體儲存方面具有傑出的表現。

A series of eight metal-organic frameworks (MOFs) based on 4,4'-stilbene dicarboxylates;4,4'-(1-fluorothane-1,2-diyl)dibenzoic acid, were synthesized under solvethermal reactions. These MOFs are following below:
[Cr3(F/OH)(H2O)2O(FDDB)3].....(1)
[Cr(OH)(FDDB)]….……...........(2)
[Al(OH)(SDC)]…………...........(3)
[Al(OH)(SDC)]…………...........(4)
[Ga(OH)(SDC)]…………...........(5)
[Al(OH)(FDDB)]………............(6)
[Al(OH)(SDC)] ….….................(7)
[Ni2(SDC)2(DABCO)].................(8)
These compounds were characterized by XRD and the particles size was measured by SEM. These MOFs were synthesized under optimized condition and long chain amines were added to improve the crystallinity. For the futhur, the compounds were studied by solid state nuclear magnetic resonance (SSNMR), thermogravimetric analyses (TGA) and fourier transform infared spectroscopy (FT-IR) ;The gas adsorption were also measured under low pressure and high pressure. The values of gas uptakes indicate these nanoporous MOFs can be good candidates for gas storage.
