The synthesis of single-molecule magnets (SMMs), magnetic complexes capable of retaining magnetization blocking for a long time at elevated temperatures, has been a major concern for magnetochemists over the last three decades. In this review, we describe basic SMMs and the different approaches that allow high magnetization-blocking temperatures to be reached. We focus on the basic factors affecting magnetization blocking, magnetic axiality and the height of the blocking barrier, which can be used to group different families of complexes in terms of their SMM efficiency. Finally, we discuss several practical routes for the design of mono- and polynuclear complexes that could be applied in memory devices.
单分子磁体（SMMs）是一类能够在高温下长时间保持磁化阻挡的磁性配合物，在过去三十年里一直是磁化学家们主要关注的对象。在这篇综述中，我们描述了基本的单分子磁体以及能够实现高磁化阻挡温度的不同方法。我们着重探讨影响磁化阻挡的基本因素、磁轴性和阻挡势垒的高度，这些因素可用于根据单分子磁体效率对不同的配合物家族进行分类。最后，我们讨论了几种可用于设计可应用于存储设备的单核和多核配合物的实际途径。
