Here, a two‐step method is reported that enables imparting new functionalities to covalent organic frameworks (COFs) by nanoparticle confinement. The direct reaction between 1,3,5‐tris(4‐aminophenyl)benzene and 1,3,5‐benzenetricarbaldehyde in the presence of a variety of metallic/metal‐oxide nanoparticles resulted in embedding of the nanoparticles in amorphous and non‐porous imine‐linked polymer organic spheres ( NP@a‐1 ). Post‐treatment reactions of NP@a‐1 with acetic acid under reflux led to crystalline and porous imine‐based COF‐hybrid spheres ( NP@c‐1 ). Interestingly, Au@c‐1 and Pd@c‐1 were found to be catalytically active.
