Abstract
A substituted polyacetylene with benzenesulfonate functional groups was synthesized from the non-catalyst polymerization of 2-ethynylpyridine using sodium 4-(2-bromoethyl)benzenesulfonate. The activated acetylenic triple bond of monomeric N-substituted-2- ethynylpyridinium bromide, formed at first quaternarization process of 2-ethynylpyridine by sodium 4-(2-bromoethyl)benzenesulfonate was susceptible to linear polymerization. Instrumental analysis datas revealed that the polymer had the fully conjugated backbone system with the designed substituents. The photoluminescence spectrum of polymer showed that the photoluminescence peak is located at 545 nm, corresponding to a photon energy of 2.28 eV.
