摘要

本研究中，以2, 5 -呋喃二羧酸(Furan-2, 5-dicarboxylic acid, H2FDA)為有機配位基，來合成新穎MOFs孔洞材並加以鑑定結構與探討性質。實驗中以鈧金屬離子與H2FDA反應，成功合成出兩個化合物：
[Sc2(H2O)2(FDA)3]••••••••••••••••••••(1)
[Sc2O(H2O)(FDA)2DMF] •••••••••••• (2)
兩個MOFs均以單晶X-ray繞射儀與粉末X-射線繞射來鑑定產物結構，利用場發射式掃描電子顯微鏡觀察產物顆粒外觀及尺寸大小。以熱重分析儀、孔徑分析儀、螢光放光與紅外光光譜儀來探討化合物特性。

In this study, we have synthesized new metal organic frameworks (MOFs) by using furan-2, 5-dicarboxylic acid (H2FDA) as a ligand and identified those structures and characterisitics.
The two MOFs, which are listed below, had been successfully created through the reation between scandium ions and H2FDA.
[Sc2(H2O)2(FDA)3]••••••••••••••••••••(1)
[Sc2O(H2O)(FDA)2DMF] •••••••••••• (2)
Structures of MOFs were characterized by Single Crystal X-ray Diffraction and Powder X-ray Diffraction (PXRD). The shape and partical size of new MOFs were identified by Field Emission Scanning Electron Microscope. The characterization for all MOFs were analyzed and determined using Thermal Gravimetric Analysis (TGA), Surface Area and Porosimetry Analyzer, Fluorescence and Fourier-Transform Infrared Spectroscopy (FT-IR)
