The preparation method comprises monomer synthesis and polymer synthesis. The polymer synthesis is that cyclopentadienyl sodium monomer is added into metallic cobalt complex-triphenyl phosphorus cobalt chloride under strict oxygen-free and water-free conditions, and then double inner alkyne or outer alkyne conjugate monomer is added in, and after reaction, the precipitation, filtering, abstersion and vacuum-drying are carried out, the large molecules polymer containing cyclopentadienyl cobaltocenium organometallic cobalt is obtained.
