The 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.
