The synthesis and characterization of a new class of nickel‐containing polymers is described. The optimized copolymerization of alkyne‐bearing nickel(II) complexes of Goedken's macrocycle (4,11‐dihydro‐5,7,12,14‐tetramethyldibenzo[b,i][1,4,8,11]tetraazacyclotetradecine) and brominated 9,9‐dihexylfluorene produced polymers with potential application as functional redox‐active materials. The title polymers exhibit electrochemically reversible, ligand‐centered oxidation events at 0.24 and 0.73 V versus the ferrocene/ferrocenium redox couple. They also display exceptional thermal stability and interesting absorption properties due to the presence of the macrocyclic nickel(II) complexes and π‐conjugated units incorporated in their backbones.
