Abstract
The first example of exchange coupling between the toroidal moments in chiral heterometallic Cu-II/Dy-III 1D polymers built from alternating trinuclear Dy-3 SMM-building blocks and chiral copper( II) complexes is reported. A very strong toroidal magnetization can be induced by applying a magnetic field at low temperature in single-crystals of these compounds.
