Nonlinear Optical Polymers Based on Polyimides Substituted with Chromophores Containing Julolidine Moiety |
| 초록 |
We prepared thermally durable NLO polymers based on polyimides appended with chromophores, which were designed to have good thermal and photochemical stability as well as high electro-optic activity. Soluble polyimides with hydroxyl group have been prepared by condensation of 2,2-bis(3-amino-4-hydroxyphenol)hexafluoropropane and oxydiphthalic dianhydride. The NLO chromophores with a terminal hydroxyl group have been synthesized by coupling between julolidine donor and alkoxy-substituted phenylenevinylene bridge, and then subsequent coupling between the resulting product and tricyanofuran acceptor. The NLO polymers showed 140-150 oC of Tgs and were thermally stable up to 200 oC, which were evidenced by DSC and TGA measurement. We obtained optical quality films by spincoating and evaluated their electro-optical properties by a simple reflection method at 1550 nm. The preliminary result showed that the polymers exhibited more than 30 pm/V electro-optic coefficient. |
