Synthesis and Properties of Conjugated Ionic Polymer with Reactive Glycidyl Functional Groups |
| 초록 |
Conjugated ionic polymer systems have potential as materials for mixed ionic and electronic conductivity, energy storage devices such as batteries and permselective membrane, and light-emitting devices, due to the their extensive conjugation and various functionalities. Here, we prepared an ionic polyacetylene with the pendent N-glycidylpyridinium bromide in 91 % yield by the activated polymerization of 2-ethynylpyridine with epibromohydrin. This polymer exhibited characteristic UV-visible absorption band at 515 nm and yellow PL spectrum at 598 nm corresponding to the photon energy of 2.07 eV. The cyclovoltamograms of polymer exhibited the electrochemically stable window in the region of -1.4 ~ 1.8 V and the redox current value gradually increased as the scan rate increased. The kinetics of the redox process of polymer was found to be well-controlled by the reactant diffusion process from the experiment of the oxidation current density of polymer versus the scan rate. |
