Abstract Photonic crystals are expected to be metamaterials because of their potential control the propagation light in linear and nonlinear regimes. Biological single‐network, triply periodic constant mean curvature surface structures considered excellent candidates owing large complete band gap. However, chemical construction these relevant is rare developing new from thermodynamically stable double‐network self‐organizing systems challenging. Herein, we reveal that shifted double‐diamond titania scaffold can achieve a The largest (7.71 %) gap theoretically obtained by shifting 0.332 c with dielectric contrast (6.25). A similar structure was fabricated using reverse core–shell microphase‐templating system an amphiphilic diblock copolymer source mixture tetrahydrofuran water, which could result 2.05–3.78 %
