Abstract | The photoisomerization of molecules is widely used to control the structure of soft matter in
both natural and synthetic systems. However, the structural dynamics of the molecules
during isomerization and their subsequent response are difficult to elucidate due to their
complex and ultrafast nature. Herein, we describe the ultrafast formation of higherorientation
of liquid-crystalline (LC) azobenzene molecules via linearly polarized ultraviolet
light (UV) using ultrafast time-resolved electron diffraction. The ultrafast orientation is
caused by the trans-to-cis isomerization of the azobenzene molecules. Our observations are
consistent with simplified molecular dynamics calculations that revealed that the molecules
are aligned with the laser polarization axis by their cooperative motion after photoisomerization.
This insight advances the fundamental chemistry of photoresponsive molecules
in soft matter as well as their ultrafast photomechanical applications.
