WebA mesogenic compound is transformed into a liquid-crystalline state, either upon heating a solid compound (thermotropic liquid crystals) or by addition of a solvent (lyotropic … WebLiquid crystals (LCs) represent a state of matter intermediate between crystalline solids, which are characterized by a regular periodic arrangement of atoms or molecules, and isotropic liquids, which lack any type of order. They exhibit varying degree of orientational and/or translational order in specific spatial directions.

Web1.1 LIQUID CRYSTALS The term liquid crystal describes a state of matter that exists between the anisotropic crystal and the isotropic liquid. The liquid crystalline or mesomorphic substances exhibit strong anisotropy in certain properties, yet maintain a certain extent of fluidity. Liquid crystals were discovered by Reinitzer (1888), Web1 apr. 2007 · In order to obtain liquid crystals with high birefringence (Δn), a series of new liquid crystals monomers incorporating styrene, a 2,5-disubstituted thiophene ring and diacetylenes, which were highly… Expand 13 Synthesis and evaluation of dinaphthylacetylene nematic liquid crystals for high-birefringence materials WebDesign of Liquid Crystal Materials Based on ... were synthesized, and their physical, chemical, optical, and photophysical properties were investigated in detail.
