Conjugated polyelectrolytes provide unique properties such as water solubility and processability, variable band gap light absorption and fluorescence, ionic interactions, and aggregation phenomena. Here, we report on the synthesis of a new conjugated polymer with ferrocene moieties by the activated polymerization of 2-ethynylpyridine using (6-bromo-1-oxohexyl)ferrocene. The chemical structure of the resulting conjugated polymer was characterized by IR, NMR, and UV-visible spectroscopies. The electro-optical and electrochemical properties of ferrocene-containing ionic polyacetylene were measured and discussed.
