    A hexaazatrinaphtylene-based transition metal complex that exhibits single molecule magnet (SMM) behaviour is reported herein. Both monometallic (1) and bimetallic (2) CoII complexes with distorted octahedral geometries could be obtained through a straightforward change in synthetic conditions. Field induced SMM behaviour was exhibited by 1, with a D value of −60 cm−1 and Ueff = 17 K originating from

  • Molecule-Based Magnets in Heterospin Systems
    作者:Noboru Koga、Satoru Karasawa
    DOI:10.1246/bcsj.78.1384
    日期:2005.8
    Our approaches to the molecule-based magnets by using heterospin systems are reviewed. In our heterospin systems consisting of the organic 2p spins and the metal ion 3d spins, various pyridines carrying the organic spins were used as binding ligands for 3d metal ions. Carbenes generated by photolysis of diazo groups and persistent N-tert-butylaminoxyl radicals were employed as the organic spin sources. First, various model complexes were prepared and their magnetic couplings between the organic spin and the metal ion through the pyridine ligand were revealed. Based on the results of magnetic studies on model complexes, ferri- and ferromagnetic complexes having linear chain structures were designed and successfully prepared. When our heterospin systems were used under solution conditions, new fields were opened. Assemblies formed in frozen solution had magnetic behaviors exhibiting slow magnetic relaxations. Especially, when the anisotropic metal ion, high-spin cobalt(II) ion, was used as the metal ion in our heterospin system, the complex formed in frozen solution functioned as a single-molecule magnet (SMM). Such formation of a monometallic SMM was the first example reported.
    回顾了我们使用异自旋系统制备基于分子的磁体的方法。在我们的由有机 2p 自旋和属离子 3d 自旋组成的异质自旋系统中,携带有机自旋的各种吡啶被用作 3d 属离子的结合配体。通过重氮基团的光解产生的卡宾和持久的N-叔丁基氧基自由基被用作有机自旋源。首先,制备了各种模型配合物,并揭示了它们通过吡啶配体在有机自旋和属离子之间的磁耦合。基于对模型配合物的磁性研究结果,设计并成功制备了具有线性链结构的磁和磁配合物。当我们的异质自旋系统在溶液条件下使用时,新的领域被打开。在冷冻溶液中形成的组件具有表现出缓慢磁弛豫的磁性行为。特别是,当各向异性属离子、高自旋钴(II)离子用作我们的异质自旋系统中的属离子时,在冷冻溶液中形成的复合物起到单分子磁体(SMM)的作用。这种单SMM 的形成是第一个报道的例子。
