Chiral cyclic compounds exhibited light-driven twisting by means of trans-cis photoisomerization in 1,4-dioxane solution, a neat film, and a liquid-crystalline host.

Single-molecule devices not only promise to provide an alternative strategy break through the miniaturization and functionalization bottlenecks faced by traditional semiconductor devices, but also a reliable platform for exploration of intrinsic properties matters at single-molecule level. Because regulation electrical will be key factor in enabling further advances development molecular electr...

Acitretin, a beneficial retinoid, was shown to undergo constant structural interconversions among its geometrical isomers (all-trans-acitretin, 9-cis-acitretin, 13-cis-acitretin, 9, 13-di-cis-acitretin, etc.) by photoisomerization under natural light. The photoisomerization was zero order reaction with an apparent velocity of 4x107 M/min under illumination by white fluorescent lamps (1, 200 lx)...

Light-driven molecular rotary motors derived from chiral overcrowded alkenes represent a broad class of compounds for which photochemical rearrangements lead to large scale motion of one part of the molecule with respect to another. It is this motion/change in molecular shape that is employed in many of their applications. A key group in this class are the molecular rotary motors that undergo u...

Photorelease and photoisomerization of trans-cinnamic acid in aqueous CTAB solutions induces a bulk solution viscosity increase and decrease, respectively, triggered by orthogonal irradiation wavelengths.
