Influence of linking units on the photo responsive studies of azobenzene liquid Crystals: Application in optical storage devices

Light-responsive bent-core liquid crystals as candidates for energy conversion and storage

“…Whilst phase transitions from ordered mesophases to disordered melts are common, see for example [75,76], we now investigate whether a combination of light and electrical fields could promote an isothermal transition between different mesophases. Even though the columnar phase cannot be transformed isothermally into a smectic phase by the mere application of electrical fields, [28,62] our results in Fig.…”

Synthesis and Characteristics of Smart Coating Materials for Reversible Double Stimulus-Responsive Oil–Water Separation

“…The characteristic absorption peaks of azobenzene compounds are mainly π−π* transition peaks of 280−370 nm and n−π* transition peaks of 420−500 nm. 67 Figures 4a, 4f, and 4g show the reversible photoisomerization of monomer 1 under a 365 nm UV lamp, a 445 nm visible lamp, and natural light irradiation at different times. It was found that, with only 14 s, a back conversion of 94.7% from cis to trans can be achieved, showing that the used 445 nm LED light source can provide a higher back conversion efficiency over time than natural light.…”
