Synthesis of an ionic polyacetylene by the activated polymerization of 2-ethynylpyridine with the ring-opening of cyclic compound |
| 초록 |
The polymers having a conjugated backbone are expected to show unique properties such as electrical conductivity, paramagnetism, migration and transfer of energy, color, and chemical reactivity and complex formation ability. Here, we synthesized an ionic polyacetylene via the activated polymerization of 2-ethynylpyridine with the ring-opening of propiolactone. The polymerl structure was characterized by various instrumental methods to have polyacetylene polymer backbone with (N-propionate)pyridium substituents. This zwitterionic polymer was soluble in such polar protic solvents as water, methanol or organic acids capable of hydrogen bonding with the propionate anion. The cyclovoltammograms of polymer exhibited the irreversible electrochemical behaviors between the oxidation and reduction peaks. The oxidation current density of polymer versus the scan rates is approximately linear relationship in the range of 30–120 mV/s. |
