Formation of trigons in a metal-organic framework: The role of metal-organic polyhedron subunits as meta-atoms.

ABSTRACT: Shape control of metal-organic materials on the meso- and macroscale has been an important theme due to emerging properties. Particularly, chemical etching has been useful to create various forms such as core-shells and hollow crystals in metal-organic frameworks. Here we present a unique chemical etching strategy to create trigonal patterned surfaces in metal-organic frameworks. The mechanism suggests that metal-organic polyhedron subunits serve as meta-atoms, playing a crucial role in the formation of trigons on the surface. Such a patterned surface in porous solids can be utilized in meta-surface applications in the foreseeable future.
