Alignment and Orientation Control of Porous Nanoparticles
- Fabrication of Two-Dimensional Superstructures by Ice Templating Method -

An international research team led by Yusuke Yamauchi, MANA Principal Investigator (Mesoscale Materials Chemistry Group), and their colleagues have successfully synthesized two-dimensional superstructures composed of metal organic frameworks (MOF) nanoparticles by the ice templating method, which utilizes the phenomenon of concentration that occurs during water solidification.

The team discovered that monolayer and bilayer two-dimensional superstructures can be obtained by controlling the concentration of the precursor MOF nanoparticle monodisperse solution. They also found that the method is applicable to various other MOF nanoparticles, and that two-dimensional superstructures can be obtained in heterogeneous MOF mixtures as well.

The ice templating method is industrially attractive due to its low cost, simplicity, and versatility, and is expected to lead to the derivation of superstructures composed of all kinds of porous nanoparticles, including MOFs.

This achievement was supported by the JST-ERATO YAMAUCHI Materials Space-Tectonics Project and was published in the Journal of the American Chemical Society on September 14, 2022.
