摘要
PolyaIilline and its derivatives is one kind of important conductive polymer.In this paper, the active mechanism of substitution and doping on conductivity of polyanilines was studied by means of EHMO-CO method. The result showed that doping and substitution had different active mechhosm on conductivity of polyedlines, doping lowered markedly the exciting energy of carrier, while substitution altered chieIly the band width.
