A facile approach for the heterogenization of transition metal catalysts using
non-covalent interactions in hollow click-based porous organic polymers
(H-CPPs) is presented. A catalytically active cationic species, [Ru(bpy)3]2+ (bpy =
2,2’-bipyridyl), was immobilized in H-CPPs via electrostatic interactions.
The intrinsic properties of [Ru(bpy)3]2+ were well retained. The resulting Rucontaining
hollow polymers exhibited excellent catalytic activity, enhanced
stability, and good recyclability when used for the oxidative hydroxylation of
4-methoxyphenylboronic acid to 4-methoxyphenol under visible-light irradiation.
The attractive catalytic performance mainly resulted from efficient mass transfer
and the maintenance of the chemical properties of the cationic Ru complex in
