自2003年以来，铽（III）双酞菁酸盐配合物被认为是单分子磁体（SMMs），促进了多项研究，目的是更好地理解在异常高阻断温度下的单金属离子磁性。在探索新应用的过程中，很明显，如果自旋电子器件是由SMM分子制成的，它们在表面或电极附近的限制将变得难以规避。在这篇展望性的文章中，我们强调了不同衬底的存在对tbpc2 - smm磁性能的影响，原则上是由电子杂化、偶极子-偶极子耦合和表面量子隧穿（QT）速率的变化等效应引起的。我们表明，对smm如何与环境相互作用和通信的更好理解最终导致磁残留和更低的隧穿率，为新型自旋电子器件铺平了道路。
Since 2003, terbium(III) bis-phthalocyaninato complexes have been recognised as acting as single molecule magnets (SMMs), propitiating multiple studies with the aim of better understanding the single metalion based magnetism with unusually high blocking temperatures. In the quest for novel applications, it became clear that if spintronic devices were made from SMM molecules, their confinement in the proximity of surfaces or electrodes would become difficult to circumvent. In this perspective article, we highlight the influence of the presence of different substrates on the magnetic performance of TbPc2-SMMs, in principle caused by, among other effects, electronic hybridization, dipole-dipole coupling and changing quantum tunnelling (QT) rates on the surface. We show that the improved comprehension of how SMMs interact and communicate with the environment finally leads to magnetic remanence and lower tunnelling rates, paving the way to novel classes of spintronic devices.
