Synthesis and photoswitching properties of liquid crystals derived from myo-inositol

Abstract

A new myo-inositol-based liquid crystal can be used for the creation of optical storage devices. The dark area is the UV-irradiated area forming a disordered isotropic phase, whereas the bright area protected from the light by using a mask remains in the ordered phase.

Photoresponsive behavior of hydrophilic/hydrophobic-based novel azobenzene mesogens: synthesis, characterization and their application in optical storage devices

“…43 The experiment was carried out in the dark at room temperature of 27 C and chloroform was used as the solvent. The unimolecular thermal cis-trans isomerisation in the dark obeys eqn (2).…”

“…Optical storage devices have attracted increasing attention in the eld of information technology over the last few years. [1][2][3][4][5] Organic photochromic compounds are used to evaluate the photoinduced behaviour of optical storage devices. 6,7 This process arises from the reversible photoinduced isomerization of a photochromic group such as azobenzene.…”

“…[28] The rate constant for the cis-trans isomerization for the compound was calculated by the following equation 1 at room temperature. [33]…”

Aliphatic/aromatic spacers based azo dye dimers: synthesis and application for optical storage devices

“…1,2 The light sensitive groups, mainly chromophores, are responsible for the photoisomerization and reorientation of molecules. [3][4][5] Among chromophores, azo dyes are good candidates for studying light-induced properties, which in turn makes it possible to create optical storage devices, due to their highly sensitive photoisomerization nature. 1 Azo dyes with different structures have been studied extensively for photoisomerization and liquid crystalline behaviour by many groups.…”
