Abstract
We selected polyamic acid as a precusor of polyimide which is highly thermally resistant and disperse red 1 as a nonlinear optical active chromophore. Two compounds that were anchored with trialkoxy silane were employed to fabricate the organic/inorganic composite film via sol-gel process. After corona poling and thermal treatment, partial imidization was completed. Resulting from the network and good thermal resistance, the molecular dipolar alignment became very stable after poling. Therefore, we developed the polyimide analogue with NLO chromophore to exhibit good temporal stability.

열 안정성이 우수한 폴리이미드의 전구체로 polyamic acid(PAA)와 이차 비선형 광학 특성이 뛰어난 disperse red 1(DR1)을 발색단으로 선택하여 alkoxy silane이 결합된 두가지 화합물을 합성한 다음 졸-겔법에 의해서 필름형태의 유기-무기 이차 복합 비선형 광학재료로 박막을 제조하였다. 코로나 분극처리 후 열처리를 통해서 매질 내의 부분적인 이미드결합을 형성시켰다. 이때 형성된 이미드결합에 의해서 망상구조와 뛰어난 열 안정성으로 말미암아 분극처리 후 발색단의 분자배향이 안정화되므로 우수한 경시안정성을 나타내는 폴리이미드계 전기광학재료를 개발하였다.
