Amphiphilic block copolymer templates in sol–gel processes yield bicontinuous silicates with distorted hexagonal symmetry (see, for example, the transmission electron migrograph depicted on the right). The long Bragg distance of 8–13 nm combined with the high mechanical and thermal stability suggests some promising prospects for chemistry and materials science.
