Non-catalyst Synthesis of an Ionic Polyacetylene via the Polymerization of 2- Ethynylpyridine by Using 4-(Bromomethyl)-7- methoxycoumarin |
| 초록 |
A new class of highly conjugated, substituted polyacetylenes was synthesized by the spontaneous polymerization of monomeric ethynylpyridinium salts without any additional initiator or catalyst. The advantage of this polymerization essentially prevents the contamination of polymer sample by residual catalyst or initiator impurities used in the process. Here, a new ionic polyacetylene with coumarin moieties was synthesized via the polymerization of 2-ethynylpyridine using 4-bromomethyl-7-methoxycoumarin in high yield. The polymer structure was characterized by such various instrumental methods as NMR, IR, and UV-visible spectroscopies to have a conjugated backbone with the designed coumarin groups. The photoluminescence peak was observed at 512 nm corresponding to a photon energy of 2.42 eV. The cyclovoltamograms of polymer exhibited the electrochemically stable window at the −1.8 ∼ 1.50 V region. |
