Precise control over molecular movement is of fundamental and practical importance in
physics, biology, and chemistry. At nanoscale, the peculiar functioning principles and the …

In the wide area of host–guest chemistry, hemicryptophanes, combining a cyclotribenzylene
(or cyclotriveratrylene CTV) unit with another different C 3-symmetrical moiety, appears as a …

Research directed toward the goal of molecular gyroscopes since the coverage of a
previous review (2002) is described. Such species are a subclass of molecular rotors, which …

Successful control of the orientation of the π-electron systems in media has been achieved
in certain liquid crystals, making them applicable to devices for optical systems because of …

Compounds 3 and 5 were synthesized according to the previously reported procedure. 1
Solvents used were of commercial grade. 1H NMR spectra were recorded at 298 K on a …

Recently, functional organic materials have been put into practical use. The application of
molecular motions has the potential to create new molecule-based materials. For this …

A macrocage molecule with a bridged phenylene rotor has been reported as a molecular
gyrotop, because the rotor can rotate even in a crystalline state. Although the most stable …

Threefold intramolecular ring‐closing metatheses of trans‐[MCl2 (P {(CH2) mCH CH2} 3)
2] are effected with Grubbs' catalyst. Following hydrogenation catalyzed by [RhCl (PPh3) 3] …

Phenylene-bridged macrocage molecules were synthesized as molecular gyrotops because
the rotor can rotate even in a crystal. The chain-length-dependent properties of the …

Hemicryptophanes are host molecules with many applications as supramolecular catalysts
or in ion selective recognition. A very convenient and efficient modular approach for the …
