Porous materials are useful in various applications including photonics, capacitors, and biological materials. Self-assembly of block copolymers enables the formation of periodic nanostructures at the mesoscale and has been widely used as templates for porous structures. Bottlebrush block copolymers with ultrahigh molecular weight can form ordered structures at larger length scales exceeding 100 nm. Herein, we report the hierarchical self-assembly of functional bottlebrush block copolymers to form ordered porous architectures with pore sizes ranging from 10 to 150 nm. By tuning the copolymer molecular weight and architecture, the resulting morphology and domain size can be systematically controlled. By adjusting the self-assembly process, the assembled superstructures vary from bulk to one-dimensional and three-dimensional materials. Selective removal of one block produces highly ordered, periodically porous structures, highlighting a versatile platform for porous materials.
