As a kind of special binuclear dysprosium single-molecule magnet ({Dy2}-SMM), the asymmetric {Dy2}-SMMs feature two Dy centers that locate in distinct ligand fields. Such an structure allows to locally modulate part while maintaining original features other parts, thus favoring more delicate and targeted tuning single-ion anisotropy center magnetic interactions between centers. Yet, they are still rare due difficulty synthesis. Herein, we report three {Dy2}-SMMs, namely, [Dy2(tmsa)(MeOsa)(H2O)2] (NO3)2·CH3OH (1), [Dy2(tmsa)(sa)2(H2O)]NO3 (2), [Dy2(tmsa)(Fsa)(H2O)2] (NO3)2·5H2O·CH3OH (3), where H3tmsa, HMeOsa, Hsa, HFsa represent tris[(3-methoxysalicylidene)aminoethyl]amine, 3-methoxysalicylaldehyde, salicylaldehyde, 3-fluorinesalicylaldehyde, respectively. They were prepared by peripheral-protected nonequivalent chelating strategy, wherein single tmsa3– uses pockets encapsulate ions providing peripheral protection. Significantly, salicylaldehyde-based auxiliary ligands bearing different substituents, including HFsa, have fine-tuned local fields successfully. 1–3 show slow relaxation behaviors, with highest efficient energy barriers (Ueff) 79, 154, 110 K, This work provides strategy for achievement new fine-tuning behavior these SMMs.

This is a critical report on the most recent progress towards implementation of single-ion/molecule magnets (SIM/SMMs) in molecular spin qubits. Short flash-back to effect lattice distortions doubly degenerate state manganites, mirrored by magnetic bistability SMMs, followed summary suppression quantum decoherence SIM/SMMs units slowing spin-lattice relaxation and avoiding level crossings.
