The article presents a dysprosium complex that is chemically designed to exhibit strong easy-axis type magnetic anisotropy preserved in dichloromethane solution at room temperature. The detailed theoretical and experimental studies explain the typical features of highly performant single molecule magnets (SMMs). The NMR characterization shows remarkably large chemical shifts, outperforming the current state-of-the-art pseudocontact shift (PCS) tags.
A common criterion for designing performant single molecule magnets and pseudocontact shift tags is a large magnetic anisotropy. In this article we present a dysprosium complex chemically designed to exhibit strong easy-axis type magnetic anisotropy that is preserved in dichloromethane solution at room temperature. Our detailed theoretical and experimental studies on the magnetic properties allowed explaining several features typical of highly performant SMMs. Moreover, the NMR characterization shows remarkably large chemical shifts, outperforming the current state-of-the art PCS tags.
