The design, synthesis, and characterization of bottlebrush block copolymers made through the ring-opening metathesis polymerization of A-<i>branch</i>-B diblock macromonomers are presented. The self-assembly of polystyrene/polydimethylsiloxane bottlebrushes was carefully studied in the bulk and in thin films. Lamellar, hexagonal cylindrical, and gyroid phases were observed and modeled. The unique A-<i>branch</i>-B bottlebrush structure provides unique advantages in the context of bottlebrush polymer self-assembly, including access to the first examples of the gyroid phase.
