A New Ionic Polyacetylene from Non-catalyst Polymerization of 2-Ethynylpyridine Using 3,4,5-Trimethoxybenzoyl chloride: Synthesis and Properties |
| 초록 |
The nitrogen-containing conjugated polymers contain the nitrogen heteroatom either in the main chains or in the side chains, which provide the facile quaternization reaction and protonation of the nitrogen sited. Here, a new substituted ionic polyacetylene was synthesized via the uncatalyzed polymerization of 2-ethynylpyridine using 3,4,5-trimethoxybenzoyl chloride. The photoluminescence peak was observed at 570 nm corresponding to a photon energy of 2.18 eV. Based on absorption spectrum, the band gap was 2.23 eV. The cyclovoltamograms of polymer exhibited the electrochemically stable window at the -1.8 ~ 1.50 V region. Oxidation and reduction were started at 0.5 and −0.9 V and this material showed stable electrochemical property up to 30 cycles. |
