A charge-transfer (CT)-type supramolecular rotor, (coronene)(2)F(4)TCNQ was obtained by vacuum co-sublimation. The CT complex has an unprecedented crystal structure consisting only of DDA-type alternating pi-columns of coronene (D) and electron acceptor (A), and coronene molecules with a pronounced undulating structure form no C H center dot center dot center dot F hydrogen bonds with adjacent F(4)TCNQ molecules in the side-by-side direction. These structural features are in contrast with those reported for (coronene)F(4)TCNQ that has DA-type alternating pi-columns, which was obtained by diffusion in dichloromethane/pentane. Coronene molecules in the present complex undergo an in-plane rotation in the gigahertz region at 233 K, which is 3 orders of magnitude faster than that in (coronene)F(4)TCNQ Furthermore, the activation energy for the rotation was found to be about half of the value reported for (coronene)F(4)TCNQ These results clearly demonstrate that dynamic properties of the assemblies (CT complexes) can be varied by changing the assembly method (crystallization method), even when the parts (molecules) used as rotator and stator components are the same.
