“…These include [{Py(CH 2 ) n NH-(CH 2 ) 10 NH(CH 2 ) n Py}] (n = 1o r2 ). [73] It has also been possible to deposit [n]rotaxanes on surfaces. This is somewhat different to the metal-organic rotaxane frameworks reported by Loeb and co-workers.…”

An enormous family of heterometallic rings has been made. The first were Cr7 M rings where M = Ni(II), Zn(II), Mn(II), and rings have been made with as many as fourteen metal centers in the cyclic structure. They are bridged externally by carboxylates, and internally by fluorides or a penta-deprotonated polyol. The size of the rings is controlled through templates which have included a range of ammonium or imidazolium ions, alkali metals and coordination compounds. The rings can be functionalized to act as ligands, and incorporated into hybrid organic-inorganic rotaxanes and into molecules containing up to 200 metal centers. Physical studies reported include: magnetic measurements, inelastic neutron scattering (including single crystal measurements), electron paramagnetic resonance spectroscopy (including measurements of phase memory times), NMR spectroscopy (both solution and solid state), and polarized neutron diffraction. The rings are hence ideal for understanding magnetism in elegant exchange-coupled systems.

“…Zheng et al reviewed how mononuclear SMM can be used as qubits, detailing main results based on Gd (in Gd POM), Tb (in TbPc 2 ) and Yb ions (in Yb(trensal)) to act as qubits. In 2017, [333] Amoretti et al also reviewed the field, with a special appendix concerning the basics of the field, i. e. various key definitions and quantum logic gates. In 2018, [334] W. Wernsdorfer et al published a comprehensive review on the use of molecular qudits in quantum algorithms (Figure 33).…”

The number of scientific articles that need to be considered to cover a research topic is ever‐increasing and quite difficult for a newcomer to assimilate. This is particularly true in dynamic discipline like Molecular Magnetism. In order to help young researchers in this field, this article proposes a "review of reviews" also known as an "umbrella review" on lanthanide‐based single‐molecule magnets (4f‐SMM). As a preamble, various bibliographic search techniques and AI‐based tools for bibliographic search, indexing, and summarization are proposed and commented. Then, the main milestones in 4f‐SMM are identified. In the core of the paper, books, book articles, and reviews dealing with 4f‐SMM are contextualized and classified by subtopics. This article is therefore proposed as a gateway to the 4f‐SMM field.

“…The first disclosure of a molecule exhibiting slow relaxation of magnetization in the absence of an external magnetic field has revolutionized magnetochemistry and opened a prolific field of research in molecular inorganic chemistry. Such single-molecule magnets (SMMs) could enable a dramatic increase in information storage density that is not feasible with current technologies, and they are thus attractive for quantum computing and spintronic applications. − State of the art SMMs are assembled from lanthanide ions, which are associated with high intrinsic magnetic moments. − This property alone is not sufficient for slow relaxation of magnetization or the associated magnetic remanence. It is the presence of magnetic anisotropy, a preferential orientation of the magnetic moment in the molecule, that differentiates a SMM from a classical paramagnetic complex.…”
