Název v původním jazyce

Dual tunability of selective reflection by light and electric field for self-organizing materials

Popis výsledku v původním jazyce

The formation, tuning and contactless control of the helix formed by chiral materials, i.e the selective reflection, is an actual and highlighted topic in soft matter supramolecular systems. The oblique helicoidal structure can be formed in right-angle cholesterics under the applied electric field. The electric field changes the pitch and cone angle but preserves the single-harmonic modulation of the refractive index. As a result, in such a supramolecular system, we can tune the selective reflection of light in a broad range. Here, we report that structural colors can be tuned by simultaneously by UV light irradiation and by the action of an electric field. The effect was explained in terms of molecular matching, Z-E isomerization, and electric field action. The designed photo-active supramolecular system may have high impact for application in soft matter UV detectors.
