碩士 === 中原大學 === 化學研究所 === 104 === In this study, we successfully synthesized a series of nanoporous metal-organic frameworks (MOFs) of iron(III) fumarate MIL-88A, iron(III) terephthalate MIL-88B, iron(III) 2,6-naphthalenedicarboxylate MIL-88C and amino-functionalized MIL-88B (labeled as MIL-88B-NH2) within 5 min only and at room temperature. These four MOFs are represented as given chemical formula in the following： [Fe(OH)(FUM)]…………(1) [Fe(OH)(BDC)]…………(2) [Fe(OH)(NDC)]…………(3) [Fe(OH)(BDC-NH2)]……(4) These MOFs have been characterized by the powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and gas adsorption measurements. In the second part, particular attention was paid to the influence of the temperature and solvent on the crystal size distribution for the above MOFs. These results have been characterized by the powder X-ray diffraction (PXRD), and scanning electron microscopy (SEM) In the third part, we used the MOF 2 to do directly carbonation in a furnace under the N2 inert gas at 700 oC ~ 1000 oC. After the carbonation, the obtained samples were structurally characterized by the powder X-ray diffraction (PXRD) and gas adsorption measurements. In the last part, a mesoporous MOF was synthesized with 4-[[(4-carboxyphenyl)imino]methyl]benzoic acid (H2CAB) and aluminum(III) were synthesized by heating in different metal to ligand (M/L) molarity ratio. The MOF have been characterized by the powder X-ray diffraction (PXRD) and gas adsorption measurements. The characterited results were examined corresponding to the different M/L ratio. The MOF iso-structure to CYCU-3 is represented as given chemical formula in the following： [Al(OH)(CAB)]…………(5)
