Rapid and Reversible Visible-Light-Induced Helix Inversion in Chiral Liquid Crystals Doped with a Negative Photochromic Molecule.

Light-induced helix inversion in chiral nematic liquid crystals (N*LCs), where helicity reverses under photoirradiation, has emerged as a promising strategy. However, existing systems often suffer from slow response times and limited reversibility, p…
