Box-like gel capsules from heterostructures based on a core–shell MOF as a template of crystal crosslinking

Abstract

New polymer capsules (PCs) were obtained using a crystal crosslinking (CC) method on core–shell MOF crystals. The latter are based on the epitaxial growth of two isostructural coordination polymers which are then selectively crosslinked. Decomposition of the non-reticulated phase leads to new PCs, possessing a well-defined hollow cubic shape reflecting the heterostructure of the template.
