Gearing motion in cogwheel pairs of molecular rotors: weak-coupling limit
Résumé
Variable-temp. (VT) crystal structures, VT 1H spin-lattice relaxation in static crystals, and DFT modeling of the rotational barriers of BCP rotators in cryst. arrays of a rod-like mol. contg. two 1,3-bis(ethynyl)bicyclo[1.1.1]pentane (BCP) units demonstrate that a correlated gearing motion occurs in the limit of a weak coupling between two rotors in a pair.
