A novel naphthalene diimide-based covalent organic framework (NDI-COF) has been synthesized and successfully exfoliated into COF nanosheets (CONs) to provide an efficient electrocatalyst for the oxygen reduction reaction.

A series of imine-based covalent organic frameworks decorated in their cavities with different alkynyl, pyrrolidine, and N-methylpyrrolidine functional groups have been synthetized. These materials exhibit catalytic activity in aqueous media for the hydrolytic detoxification of nerve agents, as exemplified with nerve gas simulant diisopropylfluorophosphate (DIFP). These preliminary results suggest imine-based covalent organic frameworks (COFs) as promising materials for detoxification of highly toxic molecules.

An imine-based covalent organic framework (COF) decorated in its cavities with uracil groups has shown selective recognition towards adenine in water. These results show how the confinement of the base-pair inside the COF's pores allows a remarkable selective recognition in aqueous media.

In order to introduce the concept of covalent organic frameworks (COFs), an important class of predictable crystalline porous polymers, an integrated laboratory experiment for advanced organic chemistry students is reported. The importance of these kind of polymers and their multiple applications are presented as a part of key concepts in polymer and organic chemistry, bridging these disciplines to materials science. Students carry out the synthesis and characterization of an iminelinked COF and its building blocks. The polymer is formed at room temperature by using solvent-assisted synthesis and mechanochemistry. Students are trained in solid state characterization techniques, including FTIR spectroscopy, thermogravimetric analysis (TGA), 13 C NMR crosspolarization−magic angle spinning (CP-MAS) NMR spectroscopy, and powder X-ray diffraction (PXRD), which are essential in the important field of reticular chemistry. Therefore, this lab experience constitutes a practical introduction to COFs.
