Absolute Helix‐Sense‐Selective Polymerization Using Circularly Polarized Light in One‐Handed Helical Channels

Absolute helix-sense-selective polymerization of an achiral acetylene monomer (1) in one-handed helical channels created with helix-sense-selective decomposition of (±)-poly1 using circularly polarized light is realized with no chiral compounds. In addition, the relative optical yield (%ee) of the formed oligomers is controlled by those of the one-handed helical channels.
