45_07/2006Cover Picture: Transcription and Amplification of Molecular Chirality to Oppositely Biased Supramolecular π Helices (Angew. Chem. Int. Ed. 7/2006)

Inversion of helicity and the formation of unusual fused supercoiled left and right helices of gel-forming linear π-conjugated molecules by a “sergeants and soldiers” approach, in which the achiral molecules (soldiers) mistake orders from the chiral molecules (sergeants), is described by A. Ajayaghosh et al. on page 1141 ff. The cover picture shows Janus, the double-faced Greek God, holding a left-handed DNA helix and a right-handed conch which epitomize the marvels of natural creations.
