摘要：

Novel polysilanes, antimony-substituted polysilanes (APS) and iron-substituted polysilanes (IPS), were synthesized and characterized in this paper. To prepare these new metal-containing polymers, high reactive polymers, polymethylsilane (PMS) and polychloromethylsilane (PCMS) were used as mother polymers. The APS was synthesized directly by the reaction of PMS with SbCl 3, while IPS was obtained from the reaction of PCMS with Na 2Fe(CO) 4 in the solvent of n-hexane. The polymers were characterized by elemental analysis, FT-IR, 1H-NMR, 29Si CP/MAS NMR, GPC, and UV. The number average molecular weights of these two polymers are between 1400 and 1600. These polymers show good semiconductive properties, whose intrinsic conductivities are in the range of 10 -8~10 -7S/cm, and can be increased to10 -5S/cm after being doped with iodine. © Xing et al.
