Syntheses, Magnetic and Luminescent Properties of Lanthanide Complexes With Low Coordination Numbers

Abstract

由于稀土元素大的离子半径,导致其稀土配合物具有丰富的拓扑结构,能够形成单核、双核、三核甚至多核的金属簇合物,该簇合物具有纳米尺寸的分子结构,表现出有趣的光、电、磁和催化性质。然而绝大多数稀土配合物的稀土离子的配位数大于7,对于配位数小于7的配合物研究报道却较少。此外,据我们所知,有关低配位数稀土配合物的发光研究报道文献目前仅有一篇。正是基于这样的研究背景,本论文选用多个大位阻的有机物作为配体合成低配位数稀土配合物,系统研究了低配位数稀土配合物的合成条件、结构特点以及磁学与发光性质。论文具体内容如下: 1.采用大位阻的三齿N-杯[3]芳烃配体,在给定的条件下合成以硝酸根为抗衡离子的九配位单核稀...Lanthanide complexes with large ion’s radius attracted numerous attentions not only because of their aesthetically appealing architectures with nano-structure and topologies including mononuclear, dinuclear, trinuclear and polynuclear complexes but also because of their photo-luminescence, electronic, intriguing magnet and catalytic properties. While a lot of efforts have been made on the synthesi...学位:理学硕士院系专业:化学化工学院_分析化学学号:2052013115156
