Inclusion compounds based on a flexible hydrogen-bonded sheet of guanidinium ions and sulfonate moieties display lamellar and tubular architectures, depending on the guest and the organic substituent attached to the sulfonate. The observed single-crystal architectures resemble lamellar and hexagonal microstructures (see picture) in block copolymers and surfactant assemblies.
