Front Cover: Multiply Twisted Chiral Macrocycles Clamped by Tethered Binaphthyls Exhibiting High Circularly Polarized Luminescence Brightness (Chem. Eur. J. 59/2022)

Three kinds of chiral cyclic compounds and their mirror-image isomers are described. The cover was created by using a “kaleidoscope” motif to project the three pairs of enantiomers in the central hexagon. The kaleidoscope is an optical device invented in the 19th century as a result of experiments on polarized light; the word “kaleidoscope”, derived from the Greek kalos “beautiful”, was used to represent the beautiful and circularly polarized luminescent (CPL) molecules.
