Modulating the Rotation of a Molecular Rotor through Hydrogen-Bonding Interactions between the Rotator and Stator

摘要

Molecular rotors have attracted attention because of their potential applications in the fields of ferroelectric, conductive, and dielectrophoresis materials and in optical molecular devices. The molecular rotors synthesized thus far can primarily be divided into two types: mono-component molecular rotors and multiple-component molecular rotors. In the former, the stator and rotator are contained within the same molecule, whereas, in the latter, the stator and rotator are contained in different molecules. Although the components and structures of molecular rotors differ, their physical properties primarily depend on the rotational dynamics of the rotators. Therefore, modulating the rotational rate of the rotator is critical to the application of molecular rotors.
