Abstract:Judicious design
of ligand scaffolds to highly anisotropic lanthanide
ions led to substantial advances in molecular spintronics and single-molecule
magnetism. Erbium-based single-molecule magnets (SMMs) are rare, which
is attributed to the prolate-shaped ErIII ion requiring
an equatorial ligand field for enhancing its single-ion magnetic anisotropy.
Here, we present an electron-rich mononuclear Er SMM, [K(crypt-222)][Er(dbCOT)2], 1 (where dbCOT = dibenzocyclooctatetraene),
that was obtained from a salt metathe… Show more
This review focused on the research of Dy2-SMMs for years and took the advantage of intricate relaxation mechanisms, manipulating strategies for synthesizing high-performance Dy2-SMMs to provide insights to design high-performance Dy2-SMMs.
