  • Superelasticity — a form of elasticity that involves a phase transition — has been observed for the first time in a pure organic crystal. The material could find applications in microfluidics.

  • Cross-linked liquid-crystalline polymers show photoinduced deformation with change in molecular shape and alignment of the polymers. Polymer materials can transduce light energy to mechanical stress by macroscopic deformation of the polymers (photomechanical effect). Mechanism of the photoinduced deformation of the polymers is investigated. Three-dimensional movements of the liquid-crystalline polymers are achieved by lamination of the polymers into a flexible polymer sheet. This review described a short overview of recent developments in photomechanical effects mainly focusing on design of the polymer materials with photochromic moiety and applications to light-driven polymer actuators.

  • The design and preparation of azobenzene-containing polymers showing a large photoinduced change in refractive index, and their applications to rewritable Raman-Nath and Bragg holograms are reviewed. Holographic performance has been remarkably improved with regard to diffraction efficiency, response time and multiplicity by development of newly designed polymer systems.

  • Macroscopic deformable materials controlled by light have been the subject of growing research interest in the last few decades due to both their fundamental properties and their wide applicability. In this review, examples of photomechanical effects in crystals, polymers, and CLCPs based on photoisomerization and photodimerization are reviewed.
