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).
