摘要：: The light-driven crawling of a molecular crystal that
can form three phases, (a, b, and g) is presented. Laser
irradiation of the molecular crystal can generate phasedependent transient elastic lattice deformation. The resulting
elastic lattice deformation that follows scanning irradiation of
a laser can actuate the different phases of molecular crystal to
move with different velocity and direction. Because the g phase
has a large Youngs modulus (ca. 26 GPa), a force of 0.1 mN
can be generated under one laser spot. The generated force is
sufficient to actuate the g-formed molecular crystals in a wide
dimensional range to move longitudinally at a velocity of about
60 mmmin1
, which is two orders of magnitude faster than the
a and b phases.
