Benzoxazole based nonlinear optical derivatives and polymers obtained therefrom |
| abstract |
The present invention provides benzoxazole derivatives and nonlinear optical (NLO) materials obtained therefrom as a novel organic NLO material having following general formula (I), which can be used as optical devices such as electro-optic modulator, optical switch, or the like for treating optical signal in optical communication industry. In order to obtain more stable NLO material, benzoxazole group having high thermal resistance is substituted as a pi conjugated unit instead of conventional stilbene or azobenzene group. A variety of NLO materials can be prepared by the synthetic process according to the present invention. <IMAGE> (I) wherein D and Ar have the same meaning as defined in the aforementioned. |
