“…Rotation, translation, localization, and assembly of spherical and complex-shaped particles in cells have been demonstrated by using polarized light. Ferroelectric and antiferroelectric LCs have been aligned using the photoalignment technique. − Photoalignment studies using azobenzene-based polymers and azo dye doped polymers as command surfaces are still actively pursued.…”

Light-driven phenomena both in living systems and nonliving materials have enabled truly fascinating and incredible dynamic architectures with terrific forms and functions. Recently, liquid crystalline materials endowed with photoresponsive capability have emerged as enticing systems. In this Review, we focus on the developments of light-driven liquid crystalline materials containing photochromic components over the past decade. Design and synthesis of photochromic liquid crystals (LCs), photoinduced phase transitions in LC, and photoalignment and photoorientation of LCs have been covered. Photomodulation of pitch, polarization, lattice constant and handedness inversion of chiral LCs is discussed. Light-driven phenomena and properties of liquid crystalline polymers, elastomers, and networks have also been analyzed. The applications of photoinduced phase transitions, photoalignment, photomodulation of chiral LCs, and photomobile polymers have been highlighted wherever appropriate. The combination of photochromism, liquid crystallinity, and fabrication techniques has enabled some fascinating functional materials which can be driven by ultraviolet, visible, and infrared light irradiation. Nanoscale particles have been incorporated to widen and diversify the scope of the light-driven liquid crystalline materials. The developed materials possess huge potential for applications in optics, photonics, adaptive materials, nanotechnology, etc. The challenges and opportunities in this area are discussed at the end of the Review.

This chapter is devoted to basic physical properties of liquid crystals (LCs), such as structure and symmetry of LCs, phase transitions, and mixture preparations. Dielectric, optical, and viscoelastic properties of LCs are reviewed, taking into account their relationship with the molecular structure and mixture content. We consider the surface phenomena and cell preparations, strong and weak anchoring conditions, and the behavior of liquid crystals in magnetic and electric fields.
