Web13 apr. 2024 · Nature is not always ambidextrous: it sometimes favors one hand, e.g., in the chirality of amino acids. In a recent issue of Cell Reports Physical Science, Wang and Sugiyama demonstrate the transformation of a crystal from achiral to chiral, where the hand of the crystal can be selected by the hand of circularly polarized light.

We demonstrate that this remote chirality is able to control the helicity of flexible [4]helicene subunits by UV–vis, CD spectroscopy, X-ray crystallography, and TDDFT calculations.
