Chiral molecules display a unique interaction with light. Here, it is presented the synthesis of two types of chiral structures based on spiro compounds, which show remarkable chiroptical activity. The structure of the (P2)-1 molecule (depicted in dark gray) shows a double helix formed by all-carbon atoms, while the (P4)-2 molecule (depicted in light gray) revealed a flexible configuration that modifies its chiroptical activity, but keeps its overall peculiar structure. For more information see the Communication by H. Xu, A. G. Petrovic, J. L, Alonso-Gómez et al. on page 11747 ff.
