Single-ion magnetism behaviors in lanthanide(III) based coordination frameworks

Single-ion magnets (SIMs) and single-molecule magnets (SMMs) are typically made up of 3d and/or 4f complexes that possess significant energy barriers to prevent the spin reversal behavior at the molecular level. SMMs/SIMs have various promising applications, including high-density information storage, molecular spintronics, and quantum computers. This article offers an overview of single-ion magnetism in lanthanide(III)-based coordination frameworks that consist of self-assemblies in one-, two-, and three-dimensions. The large magnetic moments and magnetic anisotropy of lanthanide(III) ions make them potential candidates for SIMs/SMMs. Additionally, the coordination framework structure enables multi-functionalities such as responsiveness to external stimuli, proton conduction, high structural stability, and host–guest interactions. These multi-functionalities indicate that the lanthanide(III)-based magnetic metal coordination frameworks represent an exciting platform for the development of a new generation of SIMs/SMMs.
