Abstract

Abstract : Intra‐assembly chirality transfer from a helicene onto a non‐chiral, emissive fluorenone ligand leads to circularly polarized luminescence (CPL) in a heteroleptic coordination cage. The Research Article (e202205725 ) by Guido H. Clever et al. shows that guest addition shifts and enhances the CPL effect, providing a modular platform for supramolecular materials with tunable chiroptical properties. The background, showing the "North America" emission nebula (NGC 7000) in the constellation Cygnus, was shot in the night sky over Dortmund using an apochromatic refractor telescope.
