單分子磁鐵近期發展

Recent Developments in Single Molecule Magnets

摘要


本文簡述單分子磁鐵合成上的進展。合成方法上有兩大策略:一是配位基的多樣性;另一是以多核的金屬簇為起始物。並簡介最高基態(S=51/2)[Mn_(25)O_(18)(OH)_2(N_3)_(12)(pdm)_6(pdmH)_6](Cl)_2的結構及其金屬間可 能的磁性作用。

並列摘要


The new developments in synthesis methods of single molecule magnets will be introduced. There are two important strategies in synthesis. One is taking the advantage of the flexibility of ligands, and the other is using the multinuclear clusters as starting materials such as [Mn_3O(O_2CR)_6(py)_3]^(o/+) and [Mn_(12)O_(12)(O_2CCH_3)_(16)(H_2O)_4]. The structure and magnetic interactions in [Mn_(25)O_(18)(OH)_2(N_3)_(12)(pdm)_6(pdmH)_6](Cl)_2, which has the record high spin ground state S = 51/2 in single molecule magnets, are described.
