Scissor-Tailed Block Copolymer Bottlebrushes and Their Unique Solid-State Assemblies

Provided are new bottlebrush polymers and diblock bottlebrush copolymers, which can self-assemble into structures of desired morphology (e.g., hexagonal cylindrical, gyroid). The self-assembled structures of the bottlebrush polymers and copolymers provide useful materials such as photonics (e.g., photonic crystals), functional materials, chromatography media, stimuli-responsive materials, lubricants, nanolithography, films, and coatings. In certain embodiments, the backbone repeating units of the bottlebrush polymers and copolymers have two different polymeric sidechains covalently attached to the backbone repeating unit through a branched linker, wherein one of the polymeric sidechain is a polysiloxane. Also provided are methods of preparing the bottlebrush polymers and copolymers described herein.
