Metathesis cyclopolymerization of mono‐ or bissubstituted 1,6‐heptadiynes is undergone to generate the ionic polyacetylenes (iPAs) with branched 1,2,3‐ttriazolium pendants, which possess relatively high intrinsic ionic conductivities of 1.4 × 10 −5 –2.1 × 10 −5 S cm −1 at 30 °C. The doping treatment with lithium bis(trifluoromethanesulfonyl)imide endows iPAs with enhanced ionic conductivities of 2.5 × 10 −5 –4.3 × 10 −5 S cm −1 . Further doping with iodine, iPAs show ionic and electronic dual conductivities of 4.5 × 10 −5 –7.1 × 10 −4 and 1.5 × 10 −6 –4.5 × 10 −6 S cm −1 , respectively. Therefore, the doped iPAs demonstrate the potential in the area of conducting polymers and polymeric electronics.
