A new family of substituted ionic polyacetylenes that retain extensive conjugation have been prepared through the activated polymerization of ethynylpyridines. These ionic conjugated polymers have potentials as material candidates for mixed ionic and electronic conductivity, energy storage devices such as batteries, permselective membrane, solar cells, and light-emitting devices. Here, we report on the preparation of poly(N-bromoethynylpyridinium bromide)s via the simple bromine-induced polymerization of ethynylpyridines. The chemical structure of resulting polymers was characterized by using various instrumental methods such as IR, NMR, and UV-visible spectroscopies. The electro-optical and electrochemical properties of ionic conjugated polymers were measured and discussed.
