Outline of Final Research Achievements |
Beyond the limitations of conventional transition-state studies focusing on small molecular systems in a gas or solution, we have developed a control method for transition states of chemical reactions or molecular motions in a solid (crystal). Crystalline molecular gyroscopes have an aromatic ring (rotor) encased in an exterior framework (stator) and the ring rotates around the bond axis that bridges the rotor and stator. Manipulating the fast internal rotation in molecular gyroscopes will give birth to novel optical materials. We successfully reproduced the crystal structures of molecular gyroscopes with a polar rotor and a cage-like stator, and theoretically evaluated their rotational barriers. We also performed the simulations of thermally induced and light-driven internal rotations in the molecular gyroscopes and found that continuous rotation can be achieved in several ns after the initiation of exposure to infrared lasers.
