%X 席夫碱取代基团的各向异性,C=N基团自身的优良特性,使得席夫碱配体在光电材料、磁性材料、催化活性、分析化学等领域有着非常广阔的应用前景。许多稀土离子不仅有大的基态自旋值,还有大的磁各向异性的特点,这使得稀土离子成为理想的分子磁体的制备顺源,科学家们因此一直在期待着使用稀土离子来构建分子磁铁。然而,由于稀土离子的半径较大,它们之间的相互作用通常较弱,很难获得性能良好的分子磁体。引入3d过渡金属不仅可以改善复合物的整体自旋基态,还可以改变稀土的磁交换路径。因此,过渡金属离子与稀土金属离子耦合形成的基于席夫碱配体的3d-4f金属配合物通常具有良好的磁性能。本文中首先介绍了席夫碱配体的分类,金属配合物的发展历程,稀土–过渡配合物的合成方法,并且根据不同的过渡金属离子,将稀土–过渡配合物分为六种类型,重点综述了其结构及性质,探讨稀土–过渡配合物在当前的应用及在未来的发展前景。
Schiff-based ligands have a very broad application prospect in the fields of photoelectric materials, magnetic materials, catalytic activity, analytical chemistry, etc. due to the anisotropy of substituted groups and the excellent properties of C=N groups. Many lanthanide ions not only have large ground state spin values, but also have large chain anisotropy characteristics, which make lanthanide ions an ideal source for the preparation of molecular magnets. Scientists have therefore been looking forward to using lanthanide ions to build molecular magnets. However, due to the large radius of lanthanide separation, the lease interaction between lanthanide ions is usually weak, and it is diffi-cult to obtain molecular magnets of good properties. Introducing 3d transition metals can not only improve the overall self-bonding ground state of the composite, but also change the magnetic ex-change path of lanthanide. Therefore, the Schiff-based ligand 3d-4f metal complexes formed by the coupling of the transition metal ions and the lanthanide metal ions usually have good magnetic properties. This article first introduces the classification of the Schiff-based ligands, the develop-ment of metal complexes, lanthanide-transition synthesis methods, and then according to the dif-ferent transition metal ions, lanthanide-transition complexes can be divided into six types, focusing on its structure and properties and discussing the application of lanthanide-transition complexes in the current and the prospects of development in the future.
