Imaging of intact MOF-5 nanocrystals by advanced TEM at liquid nitrogen temperature

First results on the imaging of intact metal–organic framework (MOF) pores in MOF-5 nanocrystals by aberration corrected transmission electron microscopy (TEM) under liquid nitrogen conditions are presented. The applied technique is certainly transferable to other MOF systems, permitting detailed studies of MOF interfaces, MOF–nanoparticle interaction and MOF thin films.
