New Nanosheets Study Results from Stockholm University Described (pi-pi interaction of aromatic groups in amphiphilic molecules directing for single-crystalline mesostructured zeolite nanosheets)

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Nanosheets have been published. According to news originating from Stockholm, Sweden, by NewsRx correspondents, research stated, "One of the challenges in material science has been to prepare macro-or mesoporous zeolite. Although examples of their synthesis exist, there is a need for a facile yet versatile approach to such hierarchical structures."

Our news journalists obtained a quote from the research from Stockholm University, "Here we report a concept for designing a single quaternary ammonium head amphiphilic template with strong ordered self-assembling ability through pi-pi stacking in hydrophobic side, which stabilizes the mesostructure to form single-crystalline mesostructured zeolite nanosheets. The concept is demonstrated for the formation of a new type of MFI (zeolite framework code by International Zeolite Association) nanosheets joined with a 90 degrees rotational boundary, which results in a mesoporous zeolite with highly specific surface area even after calcination. Low binding energies for this self-assembling system are supported by a theoretical analysis."

According to the news editors, the research concluded: "A geometrical matching between the arrangement of aromatic groups and the zeolitic framework is speculated for the formation of single-crystalline MFI nanosheets."
