Since the discoveries of ordered mesoporous silicas prepared using surfactants, the preparation of a wide variety of ordered mesoporous materials which are structurally, compositionally, and/or morphologically controlled has been reported one after another. Although the synthesis of mesoporous aluminophosphates (AlPOs) had been required strongly, several years had passed until the first paper on surfactant-templated mesoporous AlPOs was published. The synthesis of lamellar and hexagonal mesostructured AlPOs was achieved in 1993 and 1996 at length, respectively. Consequently, the difficulty in the mesostructural control of AlPO-based materials has been demonstrated, being quite important for further understanding surfactant-templated mesoporous materials. Lamellar mesostructured AlPOs are composed of crystalline frameworks, whereas frameworks are amorphous in hexagonal mesostructured AlPOs. Accordingly, it may be better to consider that these two materials are totally different though the syntheses are conducted by using surfactants having self-assembling abilities. This review provides an overview of surfactant-templated mesoporous materials whose main frameworks are AlPOs. The recent development of synthetic strategies is also surveyed; new synthetic routes to obtain highly ordered mesoporous AlPOs were reported and organically modified and hybridized mesoporous materials whose main inorganic frameworks are AlPOs were prepared successfully.
