説明
<jats:title>Abstract</jats:title><jats:p>Inspired by the exquisite helices in Nature, fabrication of helical materials with controlled handedness has attracted considerable attention. Herein, we report on precis synthesis of single left‐ and right‐handed helical polyisocyanides through living polymerization of achiral monomers using chiral palladium catalysts under helix‐sense‐selective manner. Mechanism study revealed that the yielded helices with opposite handedness showed different activity of the living chain end. The helix with unfavored handedness was self‐terminated, while the one with favored handedness showed high activity and could undergo chain propagation to form a high molecular weight polymer with maintained single‐handed helicity.</jats:p>
