Abstract
The first example of a porous polymer containing B-Ncovalentbonds, prepared from a tetraphene B-N monomer and biphenylas a comonomer, is reported. It was prepared using the solvent knittingstrategy, which allows the connection between the aromatic rings ofthe two monomers through methylene groups provided by an externalcross-linking agent. The new polymer exhibited micromeso porositywith an S (BET) of 612 m(2)/g, highthermal stability, and potential properties as a heterogeneous photocatalyst,since it is very active in the aza-Henry coupling reaction (>98%ofconversion and selectivity). After the first run, the catalyst improvesits photocatalytic activity, shortening the reaction time to only2 h and maintaining this activity in successive runs. The presenceof a radical in this structure that remains stable with successiveruns makes it a new type of material with potential applications asa highly stable and efficient photocatalyst.
