Conductivity of doped N-carbazolyl-substituted polysilanes

Abstract A series of N -carbazolyl-substituted silane homo- and copolymers has been prepared by Wurtz coupling. Doping with iodine on these copolymer films increases the electrical conductivity to the range 10 −6 –10 −3 S cm −1 . The conductivity depends strongly on the composition of the copolymer; it reaches the maximum value for N -carbazolyl-substituted silane homopolymer. The effects of carbazolyl group on conductivity and charge transport mechanisms in the polymer are discussed.
