Description
Yang-Ze Zheng and co-authors build twisted, light-active molecules with a carbon-based catalyst, in work from 2026. The target molecules carry four aryl rings on a carbon double bond and twist into a fixed spiral. Such axial chirality suits glowing materials and displays.
Their method starts from symmetric dialdehyde versions of the targets. A nitrogen-based catalyst breaks the symmetry in one oxidation step. Many partner groups joined the reaction under mild conditions. Products came in good yields with very high chiral purity. The glowing products also emitted circularly polarized light strongly. Add-on changes to natural products and drugs proved the method's reach. Scale-up ran smoothly in their hands.
