Cover Picture: Two‐Step Divergent Synthesis of Monodisperse and Ultra‐Long Bottlebrush Polymers from an Easily Purifiable ROMP Monomer (Angew. Chem. Int. Ed. 3/2021)

Ultra‐long bottlebrush polymers were synthesized by Yoshihiro Yamauchi, Yasuhiro Ishida et al. in their Communication on page 1528 by using ring opening metathesis polymerization and atom transfer radical polymerization. In the cover picture, the ultra‐long bottlebrush polymers with different chemical properties are shown in four colors: blue, red, green, and yellow. Key to this achievement was the use of the norbornene derivative shown in the shining background as the starting material.
