The layered and hexagonal yttrium-based surfactant mesophases templated by anionic surfactant (C(n)()H(2)(n)()(+1)OSO(3)(-) and C(n)()H(2)(n)()(+1)SO(3)(-)) assemblies were synthesized by the homogeneous precipitation method using urea. The layered mesophase is formed of a layered but curving or bending microstructure and transformed into
