Poly(2-ethynylpyridine) was synthesized in high yield via the polymerization of 2-ethynylpyridine by W-, Mo- and Pd-based transition metal catalysts. The polymer structure was characterized by various instrumental methods to have a conjugated polymer backbone system with pyridyl substituents. The photoluminescence (PL) spectra of the polymer showed that the photoluminescence peak is located at 581 nm, corresponding to a photon energy of 2.14 eV. The cyclic voltamograms of polymer exhibited reversible electrochemical behaviors between the doped and undoped peaks. The kinetics of the redox process of polymer was controlled by the diffusion process from the experiment plotting the oxidation current density of polymer versus the scan rate. Due to its extensive conjugation and ionic nature, this ionic polyacetylene has potential as materials for mixed ionic and electronic conductivity, energy storage devices such as batteries, permselective membrane, and light-emitting devices. |
