文摘
An aromatic hydrocarbon rotor without functional groups is theoretically designed. Such a molecular rotor isfree from long-range electrostatic interactions. Induced dipole interactions are the rotor-driving forces undera nonresonant excitation condition. As an example, a molecular rotor with a condensed aromatic ring, apentacene moiety mounted on a phenyl-acetylene axle that is driven by a circularly polarized electric field isconsidered. Results of simulations of the quantum dynamics of a rotor that take into account short-rangerotor-bath interactions are presented by numerically solving the density matrix equations of the rotationalmotions.
