Slow Magnetic Relaxation of Lanthanide(III) Complexes with a Helical Ligand

Abstract: Isostructural Ln(III) mononuclear complexes [Ln(NO 3 ) 2 L]PF 6 ·MeCN (Ln = Nd, Tb, or Dy; L denotes a helical hexa-dentate ligand) were synthesized, and their slow magnetic relaxation behavior was investigated. In these complexes, oblate-type Ln(III) ions are located in an axially stressed ligand field with two nitrate anions, and can exhibit single-molecule magnet (SMM) behavior. Field-induced SMM behavior was observed for Nd(III) and Dy(III) complexes under an applied bias DC field of 1000 Oe.

“…Miki Hasegawa, Takashi Kajiwara and co-workers [5] present a nice 4f-SMM family based on a helical ligand in which, surprisingly, not only the Dy III but also the Nd III derivative show SMM behavior [5]. Helicity is also the topic of the work of Boris Le Guennic and co-workers [1] in which SMM behavior is observed on a racemic form of a helicene-based molecule with a remarkable magnetic hysteresis opening.…”

“…Such multi-functionality is found in the collection of papers of this Special Issue with contributions that highlight the unprecedented magnetic properties of lanthanide-based molecules together with chirality [1], luminescence [2,3] or electrical conductivity properties [4]. Innovative synthetic routes such as the use of helical [1,5] or protonated ligands [6] together with cutting edge characterization techniques of 4f-SMM are presented [7].…”
