Chemistry - A European Journal, vol. 26, no. 29, 2020, pp. 6495-6498. https://doi.org/10.1002/chem.20200022410.1002/chem.202000224https://hdl.handle.net/20.500.14352/129756The copper-catalyzed azide–alkyne cycloaddition (CuAAC) click reaction is among the most extensively used strategies for the post-polymerization modification of COFs. This work shows a new procedure for the postsynthetic functionalization of imine-based COFs by using a heterogeneous solid–gas reaction between alkyne-functionalized COFs and azides in the absence of a copper catalyst. This new alternative represents a step forward towards a greener postsynthetic modification of COFs opening a high potential for the development of new applications.engjournal articlehttps://dx.doi.org/10.1002/chem.202000224https://chemistry-europe.onlinelibrary.wiley.com/doi/10.1002/chem.202000224embargoed access547Química orgánica (Química)Materiales2306 Química Orgánica
