Covalent triazine frameworks (CTF) are crystalline porous polymers with a very high stability. They are a subclass of the covalent organic frameworks (COF). This work shows how CTF precursors can be easily functionalized, tuning the CTF to be more selective in CO 2 sorption. The second application is the oxidative coupling of amines, using just air as the oxidant at room temperature. This is a very nice example of mild metal‐free catalysis. No light is required to activate the oxygen molecules to active superoxide radicals, initiating the very selective catalytic reaction. More information can be found in the Full Paper by H. S. Jena, P. Van Der Voort et al. on page 1548.
