Junction function: All-organic isotype heterojunctions are formed through the band alignment of polymeric carbon nitride semiconductors (CN and CNS, see scheme), improving the efficiency of charge separation and prolonging the lifetime of charge carriers. These polymeric heterostructures demonstrate an excellent performance for heterogeneous photocatalysis, as shown in a hydrogen-generation assay.
