Local Structure Evolvement in MOF Single Crystals Unveiled by Scanning Transmission Electron Microscopy

The response of metal–organic frameworks (MOFs) toward external stimuli, such as light, heat, and electrons, usually involves a local change in their structures. Although diffraction methods allow for monitoring of the overall dynamics of the crystal structure, the local environment on each crystal and specific position within the crystal remains largely unknown. Here, the collective change in the pores of MOF single crystals was visualized by …
