The 2018 Wolf Prize for Chemistry was given to Prof. Omar M. Yaghi for his revolutional contribution to “reticular chemistry via MOFs and COFs”. The discovery of reticular chemistry has brought us a new paradigm that overall structure and chemical functionality can be designed through judicious choices of secondary building units and organic linkages, instead of the combination of individual atoms with mathematical supports in structure descriptions for designing the crystals by Prof Mike O'Keeffe. The crystallinity, large permanent porosity and functionalization of the pores in MOF and MOF‐like materials have been intensively discussed since their discovery based on two principal experimental approaches, single crystal or powder X‐ray diffraction (PXRD) and nitrogen gas adsorption isotherm measurements. The electron microscopy provides structural information at local fine structure and/or individual nanocrystals unlike X‐Ray diffraction which produces in essence as average over the entire powder sample or individual crystal. The following three case studies illustrate the current the edge of MOF and MOF‐like research: a woven COF‐105 and −112 and MOF MIL‐101; a new pairwise model to explain superlattice structure observed in gas adsorption experiments on IRMOF‐74; and a new STEM study on NbO as nbo net was proposed from mathematical periodic nets and tilings but named after its reported structure.
