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 …

Molecular rotors have played an important role in recent materials chemistry. Although
several studies on functional materials containing molecular rotors have been reported for …

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 …

We review the most important achievements of the last decade in the field of steroid
synthesis in the presence of palladium catalysts. Various palladium-catalyzed cross …

Reactions of trans-Fe (CO) 3 (P ((CH2) m CH CH2) 3) 2 (m= a/4; b/5, c/6, e/8) and Grubbs'
catalyst (12–24 mol%, CH2Cl2, reflux) give the cage-like trienes trans-Fe (CO) 3 (P ((CH2) …

The synthesis, crystallization, single crystal X-ray structure, and solid state dynamics of
molecular rotor 3 provided with a high symmetry order and relatively cylindrical bicyclo [2.2 …

Various aspects of molecular motion in crystals have been extensively studied in different
research fields of chemistry as a valuable source of structural and dynamic information en …

A molecular rotor built with a stator formed by two rigid 9β-mestranol units having a 90° bent
angle linked to a central phenylene rotator has an ideal structure to examine aromatic CH/π …

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 …

The reactions of sterols (androst-5-en-3β-ol-17-one, diosgenin, and cholesterol) and their
tosylates with hydroquinone aimed at the synthesis of O, O-1, 4-phenylene-linked steroid …
