Biological scaffolds with hyperbolic surfaces, especially single gyroid and single‐diamond structures, have sparked immense interest for creating novel materials due to their extraordinary physical properties. However, the ability of nature to create these unbalanced surfaces has not been achieved in either lyotropic liquid crystals or block copolymer phases due to their thermodynamical instability in these systems. Here, we report the synthesis of a porous silica scaffold with a single‐diamond‐surface structure fabricated by self‐assembly of the poly(ethylene oxide)‐ b ‐polystyrene‐ b ‐poly( L ‐lactide) and silica precursors in a mixed solvent of tetrahydrofuran and water. The single‐diamond structure with tetrahedral interconnected frameworks was revealed by the electron crystallographic reconstruction. We assume that the formation of single networks is induced by the structural transition and related to the energetic change due to the fluctuations of the Gaussian curvature. This work may provide new insights into these biologically relevant surfaces and related self‐assembly systems.
