Ferrocenediyldimethylsilane monomer has been synthesized.A series of poly(ferrocenyl dimethylsilanes) with different molecular weights have been prepared by thermal ring|opening polymerization of 1,1′|Ferrocenediyldimethylsilane at different polymerization time. It was found that with increasing polymerization time from 5min to 60min the molecular weights of resultant poly(ferrocenyl dimethylsilanes) increase from M n=1 7×10 4 to M n=1 7×10 5. The reactions of ferrocene with tetracyanoethylene (TCNE) and the reactions of poly(ferrocenyl dimethylsilanes) with tetracyanoethylene (TCNE) were investigated by ESR. A signal with %g%≈2 was detected from resultant poly(ferrocenyl dimethylsilane)/TCNE system,which indicates the formation of poly(ferrocenyl dimethylsilane)/TCNE charge transfer complex.
