Next-generation computer technologies will require ultrahigh-density data storage devices and quantum computing based on isolated spin-carriers, so-called molecular spintronics. Single-molecule magnets (SMMs) have shown great potential for such applications. Their unique magnetic properties enable SMMs to be used in spintronics for switching from total spin up to total spin down on a molecular level, and therefore each molecule can be used as a magnetic bit of information. Although a broad community works on the design of new SMMs with improved properties, coupling of the nanoscale units to the macroscopic world remains as a key challenge. Any practical application of SMMs requires in the first step their organization in 2D or 3D networks to allow read-and-write processes. Moreover, they are very delicate molecules that break down easily and thus, they need to be protected to retain their unique magnetic properties. Owed to their crystalline nature and tunability, metal-organic frameworks (MOFs) provide an excellent means to overcome this challenge. We investigated the unprecedented incorporation of SMMs into multidimensional MOF matrixes, yielding new nanostructured composite materials that combines key SMM properties with the functional properties of MOFs. We believe that these findings might be crucial for the development of spintronics in real world applications. In this presentation we will focus on the fundamental understanding in the exciting structure-property relationships of these SMM@MOF composite materials.
