介孔布拉格反射器是用于光伏、光发射和传感的有前途的材料平台。报道了一种快速且通用的制造路线，该路线依赖于嵌段共聚物聚（异戊二烯-b-环氧乙烷）的自组装与简单的溶胶-凝胶化学相结合。该方法可以对所得无机材料的孔隙率和孔径进行扩展控制，并产生高质量的光学元件。
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.
