Mesoporous Bragg reflectors are a promising materials platform for photovoltaics, light emission, and sensing. A fast and versatile fabrication route that relies on the self‐assembly of the block copolymer poly(isoprene‐ b ‐ethylene oxide) in combination with simple sol‐gel chemistry is reported. The method allows extended control over porosity and pore size in the resulting inorganic material and results in high‐quality optical elements.
