Unprecedented water-controlled rotator-stator conversion of supramolecular rotors in crystals

The rotational dynamics, dielectric response and phase transitions of a unique crystalline supramolecular rotor are controlled by the existence/absence of guest water molecules causing prominent effects on the supramolecular interactions. Such an unprecedented rotationally bistable rotor can promote...

Summary:The rotational dynamics, dielectric response and phase transitions of a unique crystalline supramolecular rotor are controlled by the existence/absence of guest water molecules causing prominent effects on the supramolecular interactions. Such an unprecedented rotationally bistable rotor can promote the understanding of precise control of molecular rotors in crystals. A supramolecular rotor exhibits two switchable rotational states controlled by guest water in crystals.
