摘要：

A series of polysilanes containing an N,N-dimethylaminophenyl group and N-pyrrolyalkyl group as in the side chain were prepared by the Wurtz coupling polymerization. The polymerization of N-pyrrolylbutyl or N-pyrrolglhexyl-substituted dichlorosilane with sodium gave successfully the polysilanes with higher molecular weight than 10(5). The electrical conductivities of I-2-doped polysilanes were dependent on the chemical structure of the amino side chain. Moreover, by use of excess iodine, the conductivity of the polymer was enhanced. The electrical conductivity of poly [bis{6-(N-pyrrolyl)hexyl}silane] (7a) increased to a maximum value of 8 x 10(-2) S/cm. (C) 1998 Elsevier Science S.A. All rights reserved.
