Abstract Due to their unique semiconducting properties, conjugated porous organic polymers (CPOPs) have garnered significant interest in various photocatalysis applications. In this study, we synthesize three thiazolo[5,4‐ d ]thiazole (TzTz)‐linked CPOPs with polyaryl rigid cores of benzene ( CPOP1) , pyrene CPOP2 ), and triazine CPOP3 ). We investigated efficacy catalyzing visible light‐driven C−N bond formation reactions, including cross‐couplings between aryl bromides amines amination reactions from sodium azides. Among the three, only combined NiCl 2 or Ni(dtbbpy)Cl effectively facilitated these transformations. Notably, exhibited photocatalytic activities approximately six times higher than its small molecular counterpart C1 both reactions. The CPOP catalyst was easily recovered through centrifugal separation reused for five catalytic cycles minimal loss activity. Theoretical calculations revealed that deliberate structural design moieties could tune energy gap, which is crucial activity This therefore, demonstrates a novel application TzTz‐linked heterogeneous
