Abstract The flexibility and diversity of organic chemistry have yielded many materials in which magnetism can be varied. However, most methods used for changing magnetism are inefficient or destructive to the magnetic material. Here we report high-performance magnetic control of a gas-responsive single-molecule magnet (SMM). The results exhibit that the magnetic properties of the SMM can be significantly changed according to the gas environment it is in and some of the magnetic states can be reversibly transformed or coexistent in the SMM through artificial control. More importantly, the single crystalline structure of the SMM is almost the same during the transformation process except for slight change of the lattice constant. Thus, this work opens up new insights into the stimuli-responsive magnetic materials which have great prospects for application in artificial design magnetic network and also highlight their potential as smart materials.

一种新型可控磁锰基单分子磁铁

摘要 有机化学的灵活性和多样性产生了许多磁性可以变化的材料。然而，大多数用于改变磁性的方法效率低下或对磁性材料具有破坏性。在这里，我们报告了对气体响应单分子磁体 (SMM) 的高性能磁控制。结果表明，SMM 的磁性能可以根据其所处的气体环境发生显着变化，并且通过人工控制，SMM 中的某些磁态可以可逆地转变或共存。更重要的是，SMM 的单晶结构在转变过程中几乎相同，除了晶格常数略有变化。因此，
