This communication reports the first integration of two significant concepts, “macromolecular helicity‐derived chirality,” and “magneticity” in one single microsphere entity. The novel chiral magnetic composite microspheres consisted of magnetic Fe 3 O 4 nanoparticles and optically active helical substituted polyacetylene. Therefore, they exhibited both remarkable optical activity and magneticity. The microspheres adsorbed (R)‐(+)‐1‐phenylethylamine much more quickly than the other enantiomer, demonstrating the potential applications of the chiral magnetic composite microspheres in chiral recognition and chiral resolution.
