1,2,3,5-Tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN)-based porous organic polymers for visible-light-driven organic transformations in water under aerobic oxidation
A novel stable radical cation triarylaminiumsalt able to induce aerobic oxidative α-C–H functionalization of tertiary amines in catalytic amounts has been developed. The reaction is performed in the absence of any other additives under mild conditions and only requires atmosphere air as a sustainable co-oxidant.

heterogeneous photocatalyst via a radical polymerization process is described, and its catalytic activity was evaluated for the aerobic phosphonylation reaction of N-aryl tetrahydroisoquinolines under visible light irradiation.
A photoelectrochemical cell is able to save nearly 90% external bias input to realize activation of P–H/C–H bonds for cross-coupling hydrogen evolution as compared with an electrochemical cell.
