The design and synthesis of fully conjugated covalent organic cages (cCOCs) featuring sp² carbon connections pose significant challenges due to the difficulties associated with forming stable CC bonds. In this study, we present a novel anthracene-based cCOC linked by CC bonds, synthesized directly through Knoevenagel condensation. Remarkably, this sp²c COC has shown exceptional performance as an n-type semiconductor, characterized by strong electronic delocalization, an optimized band structure, and extensive light absorption capabilities. It efficiently catalyzes the photodegradation of organic dyes and promotes the photoinduced aerobic oxidation of amines to imines. In comparison to imine-linked cCOCs with the same skeleton, the sp²c COC demonstrates distinct advantages as a next-generation photocatalyst, including enhanced chemical stability and superior photocatalytic performance. This research underscores the potential of Knoevenagel condensation in the development of innovative cCOCs, offering valuable insights for their applications in optoelectronic materials and catalysis.
