We finally published the research related to our old finding of shape-memory porosity when the flexible MOF crystal was being downsized. This time we correlated such phenomena with the crystal morphology.
In this manuscript, we used the solid-state molecular diffusion technique to regulate the position of pillar linkers in an individual MOF nanocrystal, in which two distinct frameworks of 2D grid layer MOFs and 3D interpenetrated MOFs coexist. The resulting nanocrystals showed dynamic structural deformation in response to guest molecule accommodations and its behavior changes depending on the ratio of two frameworks.
This research was totally implemented by our former postdoc, Dr. Kenji Sumida and our former technical stuff, Ms. Nao Horike!! Congratulations, both!!
