A woodpile structure, a similar layered structure with an unidentified space group similar to the 070 space group (Fddd), was observed in a BCP/aluminosilicate assembly [9]. In contrast to the perforated lamellar structure, zig-zag cylinders are stacked layer-by-layer (see Fig. 2). Although a zig-zag cylinder is usually energetically less stable than a parallel cylinder due to larger interfacial energy, the relaxed chain conformation of polymer chains, leading to a reduced entropic penalty, may allow the zig-zag cylinder formation.
