The spatial organization of porous coordination polymer (PCP) crystals into higher-order structures is critical for their integration into separation systems, heterogeneous catalysts, ion/electron transport and photonic devices. Here, we demonstrate a rapid method to spatially control the nucleation site, leading to the formation of mesoscopic architecture made of PCPs, in both two and three dimensions. Inspired by geological processes, this method relies on the morphological replacement of a… 

Diffusion-coupled molecular assembly: structuring of coordination polymers across multiple length scales.

This work demonstrates the structuring of a box-type superstructure comprising of a solid-solution PCP by integrating a bidirectional diffusion of multiple organic ligands into molecular assembly and demonstrated that the box superstructures enhanced the mass transfer kinetics for the separation of hydrocarbons.

Ordered macro-microporous metal-organic framework single crystals

This work constructed highly oriented and ordered macropores within metal-organic framework (MOF) single crystals, opening up the area of three-dimensional–ordered macro-microporous materials (that is, materials containing both macro- and micropores) in single-crystalline form.

Structuring of metal-organic frameworks at the mesoscopic/macroscopic scale.

Because the key issue for structuring of MOFs is to spatially control the nucleation process in desired locations, this review conceptually categorizes the available synthetic methodologies from the viewpoint of the reaction system by categorizing them into four dimensionalities, zero-dimensional (0D), one- dimensional (1D), two-dimensional, and three-dimensional superstructures.
