Abstract

Nanoscale molecular rotors that can be driven in the solid state have been realized in Cs₂([18]-crown-6)₃[Ni(dmit)₂] ₂ crystals. To provide interactions between the molecular motion of the rotor and the electronic system, [Ni(dmit)₂]^- ions, which bear one S = 1/2 spin on each molecule, were introduced into the crystal. Rotation of the [18]crown-6 molecules within a Cs₂([18]crown-6) ₃ supramolecule above 220 K was confirmed using X-ray diffraction, NMR, and specific heat measurements. Strong correlations were observed between the magnetic behavior of the [Ni(dmit)₂]^- ions and molecular rotation. Furthermore, braking of the molecular rotation within the crystal was achieved by the application of hydrostatic pressure.
