Single crystalline hollow metal–organic frameworks: a metal–organic polyhedron single crystal as a sacrificial template†
Abstract
Single crystalline hollow metal–organic frameworks (MOFs) with cavity dimensions on the order of several micrometers and hundreds of micrometers were prepared using a metal–organic polyhedron single crystal as a sacrificial hard template. The hollow nature of the MOF crystal was confirmed by scanning electron microscopy of the crystal sliced using a focused ion beam.
