Abstract Helical polymer‐containing bottlebrush polymers (BBPs) are a special and fascinating type of polymer. They possess topology contain helical as main chains (MCs) or side (SCs), thereby presenting interesting fantastic properties, such chiral amplification, circularly polarized luminescence, photonic crystal, so on. This review mainly focuses on BBPs containing polypeptides, polyacetylenes (PAs), polyisocyanides (PIs). Detailed summarizations severally given to with polypeptides MCs SCs. Meanwhile, comprising PAs fully discussed. What's more, consisted PIs SCs described separately. In addition, other briefly introduced, too. The authors hope this will motivate more interest in developing complex topologies encourage further progress functional materials.
