文摘

Experiments are described that introduce students to the important concepts of host鈥揼uest chemistry and size exclusion in porous metal鈥搊rganic frameworks (MOFs). The experiment has been successfully carried out in both introductory and advanced-level inorganic chemistry laboratories. Students synthesized the porous MOF, 伪-Mg₃(O₂CH)₆, and examined its ability to take up a variety of small organic molecules into its pores using ¹H NMR spectroscopy. The MOF exhibited size exclusion and students rationalized this behavior based on the structures of the organic molecules and the pore size of the MOF.
