The synthesis of a platinum diketonate‐based alternating copolymer containing a fluorene unit and its oxygen‐resistant phosphorescence are reported. The polymerization is executed via palladium‐catalyzed Suzuki−Miyaura coupling reaction. The synthesized polymer shows good solubility in common organic solvents and processability to form homogeneous films. By optical measurements it is found that the synthesized polymer shows phosphorescence from a triplet π–π* ligand‐centered transition, and interestingly, the emission is hardly influenced by oxygen. Phosphorescence is observed from both solution and film samples under aerobic conditions. The new idea of obtaining emissive materials based on conjugated polymers showing oxygen‐resistant phosphorescence is presented here.
