Recent studies have shown that mononuclear lanthanide (Ln) complexes can be high-performing single-molecule magnets (SMMs). Recently, there has been an influx of mononuclear Ln alkoxide and aryloxide SMMs, which have provided the necessary geometrical control to improve SMM properties and to allow the intricate relaxation dynamics of Ln SMMs to be studied in detail. Here non-aqueous Ln alkoxide and aryloxide chemistry applied to the synthesis of low-coordinate mononuclear Ln SMMs are reviewed. The focus is on mononuclear Dy alkoxide and aryloxide SMMs with coordination numbers up to eight, covering synthesis, solid-state structures and magnetic attributes. Brief overviews are also provided of mononuclear Tb , Ho , Er and Yb alkoxide and aryloxide SMMs.
最近的研究表明,单核镧系元素(Ln)配合物可以成为高性能的单分子磁体(SMM)。最近,单核Ln醇盐和芳氧基SMM大量涌现,它们提供了必要的几何控制,以改善SMM性能,并能够详细研究Ln SMM复杂的弛豫动力学。本文综述了应用于合成低配位单核Ln SMM的非水Ln醇盐和芳氧基化学。重点是配位数高达8的单核Dy醇盐和芳氧基SMM,涵盖合成、固态结构和磁属性。还简要概述了单核Tb、Ho、Er和Yb醇盐及芳氧基SMM。
