Syntheses and Properties of Poly(diphenylacetyene)s with Electron-Donating Alkoxy and Electron-withdrawing Fluoroalkyl Groups |
| 초록 |
New poly(diphenylacetylene)s with alkoxy and fluoroalkyl groups as an electron-donating and electron-withdrawing groups were synthesized with TaCl5-n-Bu4Sn and WCl6-Ph4Sn catalysts. The phenylacetylene monomer with strong electron-withdrawing difluorophenyl group was found to give high molecular polymer by both Ta and W transition metal catalyst. however, the monomers with relatively low dipole moment, i.e. less strong electron donating or withdrawing group were only polymerized with W metal catalyst. It was also found that the polymer synthesized with Ta catalyst exhibited red shifted PL spectra compared to the W catalyzed polymer. |
