Crystal Growth: Principles of Crystallization

5.6K
Crystallization is a phase transformation process in which crystals are precipitated from a supersaturated solution or formed from other sources. During crystallization, atoms or molecules arrange themselves into a well-defined, rigid crystal lattice to minimize energy.
Initiating crystallization involves manipulating the concentration of the solute and the temperature of the solution. Since crystal growth occurs when the ratio of concentration and solubility of the solute in the solvent...

Phase Transitions: Melting and Freezing

11.6K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Area of Science:

  • Materials Science
  • Organic Chemistry
  • Condensed Matter Physics

Background:

  • Liquid crystals exhibit unique optical properties influenced by molecular ordering.
  • Azobenzene compounds are known for their photoresponsive isomerization.
  • Chiral molecules can exhibit ferroelectric properties.

Purpose of the Study:

  • To investigate electric-field-induced birefringence in a novel chiral azobenzene liquid crystal.
  • To explore the stabilization mechanism of liquid-crystalline organization by ferroelectric ordering.
  • To demonstrate dual control of birefringence using electric fields and UV light.

Main Methods:

  • Synthesis of an azobenzene liquid-crystalline compound with peripheral chiral centers.
  • Application of in-plane electric fields to induce birefringence in the isotropic phase.
  • Irradiation with UV light to induce photoisomerization and erase birefringence.

Main Results:

  • The compound exhibited electric-field-induced birefringence in the isotropic liquid phase.
  • Polar ferroelectric molecular ordering stabilized the liquid-crystalline organization.
  • A novel switching mode from isotropic to homogeneous birefringent texture was observed.
  • UV light irradiation induced photoisomerization, reversibly erasing the birefringence.

Conclusions:

  • The chiral azobenzene liquid crystal shows potential for novel liquid crystal display applications.
  • Dual control of birefringence by electric fields and light offers new functionalities.
  • Ferroelectric ordering plays a key role in the observed electro-optic response.
