crystal and UV light was exposed, resulting in the scattering of the beads by deformation and bursting of the hollow structure as shown in Fig. 25.19. This is the first
example of the utilization of photosalient phenomena.
25.6 Summary
This chapter mainly described the photomechanical behavior of photochromic
diarylethene molecular crystals. The photomechanical motions are contraction, elongation, bending, separation, twisting, curling, and so on. Among them, the bending is
the most common photomechanical motion. The bending velocity largely depends on
