Chiral functional organic materials are usually prepared from chiral molecules as starting materials. Unfortunately, chiral molecules are often difficult to source and are more expensive than achiral or racemic molecules. In their Full Paper on page 681 ff. , Yoshitane Imai and co‐workers report a spontaneously resolved chiral fluorescent system prepared from achiral 4‐(2‐arylethynyl)‐benzoic acid and racemic (rac)‐1‐phenylethylamine. This chiral supramolecular organic fluorophore emits circularly polarized luminescence (CPL) in the solid state, in contrast to many other organic fluorophores.
