Conjugated polymers attract a particular attention as promising materials for photovoltaics, displays, lasers, nonlinear optical materials, chemical sensors, and realted applications as well as for gas separation and permeation membranes. Here, an ionic conjugated polymer with aromatic functional groups was synthesized via the non-catalyst polymerization of 2-ethynylpyridine by using 4-(methylthio)benzyl bromide without any additional initiator or catalyst. The polymerization proceeded well in polar solvents such as DMF, DMSO, NMP and pyridine, and produced high yields. The polymer structure was characterized to have a conjugated polymer backbone system containing N-(4-(methylthio)benzylpyridinium bromide as substituents. The cyclovoltammograms of the polymer exhibited an electrochemically stable window in the -1.32 to 1.92 V region. The photoluminescence maximum peak of polymer was located at 508 nm, which corresponds to the photon energy level of 2.44 eV. |
