Abstract
ABSTRACTThe branched triazole group is synthesized by click chemistry via a controlled approach of slow addition of AB2 compound to a B2 core, and used as the substituent for 1,6‐heptadiyne monomer. Metathesis cyclopolymerization of monomer is performed well in dichloromethane without the weakly coordinating additive, indicating that the branched triazole itself can stabilize the living propagating chain, to generate branched triazole pendant‐contained polyacetylene with trans‐double bonds and five‐membered ring repeating units along the conjugated backbone. The LiTFSI doped polyacetylenes display ionic conductivities of 2.5–1.8 × 10−6 S cm−1; by further doping with iodine, polyacetylenes show the improved ionic and electronic conductivities of 1.3 × 10−5 and 2.1 × 10−7 S cm−1 at 30 °C, respectively. Therefore, these doped polyacetylenes may act as the new electrolyte materials. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2017, 55, 485–494
