Synthesis and Electrochemical Properties of Conjugated Ionic Polymers |
| 초록 |
An ionic conjugated polymer with azobenzene moieties, was synthesized by the self-activated anionic polymerization of 2-ethynylpyridine with 4-[4-(6-bromohexyloxy)phenylazo]benzonitrile. The polymerization proceeded well in DMF solvent at the temperature of 100 oC, to give in relatively high yield (79%), even without an additional catalyst. The polymerization solution became more viscous and dark brown, as the reaction proceeded. The photoluminescence spectrum showed that the PL peak is located at 542 nm corresponding to the photon energy of 2.29 eV. The cyclovoltamograms of this polymer exhibited the irreversible electrochemical behaviors between the doping and undoping peaks. The oxidation current density of PEPB versus the scan rate is approximately linear relationship in the range of 30 mV/sec ~ 120 mV/sec. |
