چکیده
Reversible handedness inversion is achieved in self-organized helical superstructures using a visible-light-driven macrocyclic chiral switch, as reported by Quan Li and co-workers their Research Article (e202216600). Green blue light can drive the reversible switching between left- right-handedness via cis/trans photoisomerization of azobenzene within cyclic molecular switch.

Light-driven reversible handedness inversion in self-organized helical superstructures.
We report here a fast-photon-mode reversible handedness inversion of a self-organized helical superstructure (i.e., a cholesteric liquid crystal phase) using photoisomerizable chiral cyclic dopants. The two light-driven cyclic azobenzenophanes with axial chirality show photochemically reversible trans to cis isomerization in solution without undergoing thermal or photoinduced racemization. As c...
متن کاملVibrationally induced inversion of photoelectron forward-backward asymmetry in chiral molecule photoionization by circularly polarized light
Electron-nuclei coupling accompanying excitation and relaxation processes is a fascinating phenomenon in molecular dynamics. A striking and unexpected example of such coupling is presented here in the context of photoelectron circular dichroism measurements on randomly oriented, chiral methyloxirane molecules, unaffected by any continuum resonance. Here, we report that the forward-backward asym...
متن کاملLight-directing omnidirectional circularly polarized reflection from liquid-crystal droplets.
Constructing and tuning self-organized three-dimensional (3D) superstructures with tailored functionality is crucial in the nanofabrication of smart molecular devices. Herein we fabricate a self-organized, phototunable 3D photonic superstructure from monodisperse droplets of one-dimensional cholesteric liquid crystal (CLC) containing a photosensitive chiral molecular switch with high helical tw...
متن کاملChiral templating of self-assembling nanostructures by circularly polarized light.
The high optical and chemical activity of nanoparticles (NPs) signifies the possibility of converting the spin angular momenta of photons into structural changes in matter. Here, we demonstrate that illumination of dispersions of racemic CdTe NPs with right- (left-)handed circularly polarized light (CPL) induces the formation of right- (left-)handed twisted nanoribbons with an enantiomeric exce...
متن کاملVariation in the circularly polarized light reflection of Lomaptera (Scarabaeidae) beetles
An extended spectroscopic study on the left-through-left circularly polarized reflection spectra of a large number of beetles from the Australasian Scrabaeidae:Cetoniinae of the Lomaptera genus was undertaken. We have obtained a five-category spectral classification. The principal spectral features, which even within the genus range from blue to infrared, are related to structural chirality in ...
