Because the conjugated polymers contain extensive conjugation and ionic nature, these polymers have potentials as material candidates for mixed ionic and electronic conductivity, energy storage devices such as batteries, permselective membrane, and light-emitting devices. An ionic polyacetylene was synthesized in high yield via the non-catalyst polymerization of 2-ethynylpyridine using 3-(trimethylsilyl)propargyl bromide. The activated acetylenic triple bond of N-substituted-2-ethynylpyridinium bromide, formed by the reaction of 2-ethynylpyridine and 3-(trimethylsilyl)propargyl bromide, was susceptible to linear polymerization, followed by an identical propagation step that contains the produced macroanion and quaternized monomeric species. The cyclic voltammogram of polymer revealed that it shows stable electrochemical window in the range of of −1.85 V to 1.55 V. This polymer showed characteristic wide UV-visible absorption band and green PL maximum value at 518 nm, which is corresponding photon energy of 2.39 eV. |
