Colorful : Enabled by their reduced capacity for chain entanglement, high‐molecular‐weight brush block copolymers can rapidly self‐assemble to photonic crystals. The blending of two polymers of different molecular weight can predictably modulate the sizes of the polymer domains, giving rise to a facile means of precision tuning of these photonic‐band‐gap materials.
