E.; Rodriguez-Molina, B. ?Isotropic Rotation in Amphidynamic Crystals of Stacked Carbazole-Based Rotors Featuring Halogen Bonded Stators? Chem. Commun. 2016, 52, 12833-12836, DOI: 10.1039/c6cc07379d.
iquid-like dynamics of a covalent 1,4-phenylene rotator have been unveiled in 1 with a brominated stator showing type-II halogen bonds. This singular rotation is favored by synergistic molecular changes in stacked molecules, according to VT solid state NMR, 1H T1 relaxometry and VT X-ray experiments of this highly crystalline compound.
