Abstract

Abstract: A spiropyran‐based switchable ligand isomerizes upon reaction with lanthanide(III) precursors to generate complexes with an unusual N3 O5 coordination sphere. The air‐stable dysprosium(III) complex shows a hysteresis loop at 2 K and a very strong axial magnetic anisotropy generated by the merocyanine phenolate donor. Abstract : Spiropyran‐based switchable ligand : The 4f ion‐induced isomerization of a spiropyran ligand produces a mononuclear merocyanine dysprosium complex with single‐molecule magnet behavior. The air‐stable dysprosium(III) complex shows a hysteresis loop at 2 K and a very strong axial magnetic anisotropy generated by the merocyanine phenolate donor.
