Surfactant-Assisted Mesostructural Variation by the Molecular Structure of Frameworks

Typical syntheses for the mesostructural design were performed with strategic deviations, being substantially powerful for changing the molecular structure of frameworks, from the synthetic conditions optimized for the preparation of lamellar and 2-d hexagonal mesostructured materials where the frameworks were constructed by aluminophosphate (AlPO) like units with and without organic groups in the molecular scale. A series of the materials such as mesostructured aluminum organophosphonate (AOP) and AlPO type ones were investigated according to the molecular structure and crystallinity of inorganic-organic hybrid and non-hybrid inorganic frameworks. Considering a uniqueness of AlPO based frameworks, a rational insight on strength of interactions between crystalline/amorphous AlPO based units and cationic surfactant molecules was surveyed as one of the most significant factors for understanding the mesostructural variation.
