Magneto-chiral dichroism in a chiral twistacene ytterbium(iii) one-dimensional assembly of single-molecule magnets.

ABSTRACT: Here we report on one-dimensional nano objects of formula [Yb(hfac)₃(M-or P-Ant-C8)] _n where the Ant-C8 moiety refers to enantiopure M- and P-twistacenes decorated at positions 2,6 with 4-pyridyl-ethynyl units and helically locked into an end-to-end twist by an octyl tether. The crystal structure analysis reveals intertwined 1D nano-chains featuring two crystallographically independent Yb(iii) ions. Under applied magnetic fields these systems show slow relaxation of the magnetization. The optical properties show the expected contributions of the ²F_7/2 ← ²F_5/2 electronic transition of the Yb(iii) ions split by the crystal field.
