  Rotary Molecular Motors: A Large Increase in Speed through a Small Change in Design

  摘要：

  Reducing the steric interaction between the upper-half and the lower-half of a light-driven rotary molecular motor by decreasing the size of the aromatic moiety in the upper-half from a naphthalene to a benzothiophene results in an almost 3500 times faster rotation.
