    Abstract: 摘要 Schiff 鹼為醛類或酮類與第一級的有機胺類反應形成的亞胺類, 此亞胺類具有氮及氧原子可作為配位原子的二負四芽鉗合配基,而 Cr(salen) complexes 即是Schiff 鹼鉗合鉻金屬的均勻系觸媒,此金屬 鉻之salen complexes 可進行二氧化碳固定作用反應 本論文主要是以植入金屬鉻之salen complexes 於微孔洞金屬磷 酸鹽沸石:[Fe4(OH)3(HPO4)2(PO4)3] [H3N (CH2)3NH3]2?xH2O(x~9)中 形成之非均勻系鉻觸媒之研究,先成功地將微孔洞金屬磷酸鹽中的 (H3NCH2 CH2CH2 NH3)官能基與CrCl3·H2O 以離子交換的方式置換 後,進一步地加入Schiff 鹼以合成金屬鉻之salen complexes 於微孔洞 磷酸沸石材料中,Fe4P5[Cr(salen)Cl],再以粉末X-光繞射(XRD)、原 子吸收光譜分析(AA)及熱重分析(TGA)來分析其結構與組成,然而, 礙於孔洞的大小並非所有的Schiff 鹼皆可以成功地在微孔洞磷酸鹽 中形成金屬鉻之salen complexes。 Abstract Schiff base is an imine which can be synthesized by reacting aldehyde or ketone with primary amine. It is a dianionic tetradentate ligand. Cr(salen) complexes are known to be active homogeneous catalysts in the chemical fixation of carbon dioxide. The immobilization of Cr(salen) complexes via [Fe4(OH)3(HPO4)2 (PO4)3] [H3N (CH2)3NH3]2?xH2O(x~9) encapsulation in intraframework space makes it a possible way to form the heterogeneous catalyst. First, we have successfully immobiled of Cr3+ via their encapsulation in intra- framework space by ionic exchanged. The Cr3+ souced from CrCl3·H2O. Second, we added Schiff base into above-mentioned microporous metal phosphates, and we got the heterogeneous catalyst: Fe4P5[Cr(salen)Cl]. The catalysts are characterized by X-ray diffraction (XRD), atomic absorbption (AA) and thermogravimetric analysis (TGA).
