摘要：
Two polysilanes with tetrathiafulvalene (TTF) as pendant groups were synthesized by reaction of 2-cyanoethyl substituted TTF 1 with (chloromethylphenyl)dimethyl(phenyl) polysilane, or reaction of 4-vinylphenyl-TTF 2 with poly[methylsilane-co-methyl(phenyl)silane]. The structures and properties of TTF-polysilanes and their intermediates were characterized by (1)H NMR, mass, GPC, UV/Vis, IR and cyclic voltammetry (CV). The results of UV/Vis and CV of these polysilanes indicated interaction between the TTF moieties and sigma-electron delocalized Si-Si chain in the ground states. These polysilanes doped by I(2) exhibited high conductivities (10(-2) S cm(-1)).
