Ferrocene‐based polymers have drawn much attention in the past decades due to their unique properties and promising applications. However, the synthesis of hyperbranched polymers is still a great challenge. Here, two ferrocene‐based hyperbranched polytriazoles with high molecular weights are facilely prepared by the click polymerization reactions of ferrocene‐containing diazides ( 1 ) and tris(4‐ethynylphenyl)amine ( 2 ) using Cu(PPh 3 ) 3 Br as catalyst in dimethylformamide at 60 °C for 5 and 9 h in satisfactory yields of 54.0% and 52.3%. The resulting polytriazoles are soluble in common organic solvents and thermally stable, with 5% weight loss temperatures up to 307 °C. They can be used as precursors to produce nanostructured ceramics with good magnetizability by pyrolysis at elevated temperature.
