2D covalent organic frameworks (COFs) are a class of crystalline, porous, polymeric materials that have demonstrated promise in a variety of energy storage applications. The use of fluorine‐containing monomers produces 2D‐COFs with not only greatly improved surface areas (over 2000 m2 g −1 compared to 760 m2 g −1 for the non‐fluorinated analogue), but also with improved crystallinity and larger, better defined pore diameters. In their Communication on page 4255 ff., R. A. Smaldone et al. report on the formation of these COFs under varying reaction times and temperatures to obtain a greater insight into their mechanism of formation.
