摘要: | 本計畫主要目的及內容, 是分子設計具有磁性與生化活性模型金屬錯合物。分成兩大部 份,主要內容如下: (I).分子磁性: 1)有機自由基, R-(NO·)x 及其金屬錯合物物,其中R為多配位座配位子,金屬 包括:Ag,與Ln(稀土金屬)等. 2) 金屬錯合物磁構造之關連性之研究:對於架橋.核或四 核金.錯合物之M-O-M 鍵角及.配位面角與磁交換作用2J 之線性關係之探討。3) 核多核單分子與1-D, 2-D 或3-D 多核金屬錯合物之磁性研究: 一系列異金屬核單分 子:[Ln(dmf)3(H2O)3][M(CN)6]xH2O( Ln=La ~ Yb, M = Fe(III), Cr(III) , Mn(III).有趣巨大分 子設計及奈米晶體工程(nano-scale crystal engineering) ;利用含CN-架橋基, 或O, N 原 子多配位座配位子及架穚基,與金屬形成多金一維、二維及三維晶體或奈米金屬簇結構, 並探討塊狀晶體與奈米大小之磁性。 (II). 生化活性之分子設計: Catechol dioxygenase 模型Fe(III)錯合物合成、晶體構造解 析、物性與Catecholates 生化氧化反應。 The main proposes and the contents of this research project are including (I) the molecular design of molecular material of magnetism with architectures and biochemical model metal complexes. There are dived to two parts: I. Molecular magnetism: 1) stable organic radicals such as R-NO or semiquinone , where R are the multi-coordination sites ligands , and their metal- complexes (metal ions :Ag, Ln( = lanthanide metals). 2) Magnetostructural correlations between M-O-M angles with dihedral angles of coordination planes of dinuclear or tetranuclear metal complexes are studied. 3) Ln-NC-M linked metal-complexes [Ln(dmf)3(H2O)3] [M(CN)6]XH2O ( Ln = La ~ Yb, M = Fe(III), Cr(III), and Mn(III)) have been prpeared and their magnetic properties for bulky and nano-size crystal engineering architectures are investigated. II. Biochemical model metal complexes: spectroscopic studies of catechol dioxygenase-like model Fe(III) complexes: the preparations, crystal structure, and biochemical reactions with catecholates of the model Fe(III) complexes are investigated |
