However, one of the major concerns in device performance is how to maintain long-term thermal and temporal NLO stability at elevated temperatures. In this research, a fluoro-containing organosoluble and high glass temperature (251 oC) polyimide consisting of side chain reactive groups was synthesized. The reactive hydroxyl groups provide the potentiality for further chemical incorporation. Herein, the hydroxyl groups were reacted with an isocyanate-containing chromophore (DO3-ISO) to form an NLO-active side chain polyimide (PIDO3). Due to the relaxation of side chain chromophores and loose packing order of main chain, the PIDO3 sample reveal poor thermal property (Tg = 165oC). In order to enhance thermal stability, the NLO-active polyimide/inorganic semi-interpenetrating polymer network was prepared to serve the purpose of restricting molecular movement via incorporating inorganic alkoxysilanes. With the inorganic content up to 50%, the Tg of PIPT could increase to 184 oC. On the country, the dye content of PIPT decreased to 13.6% and relatively lower electro-optical coefficient (r33, 5.2 pm/V) was obtained.
本研究先合成出一个高Tg (251 oC)有机可溶的聚亚醯胺，将含有-OH官能基的聚亚醯胺与含有-NCO官能基的发色团基反应，合成出典型的侧链型二次非线性光学材料(PIDO3)，此类型的材料具有容易配向成膜、低介电常数及良好的透光率等优点，但由於侧链悬挂发色团基的基团，导致高分子链段无法形成紧密的堆叠，因此材料的热性质呈现快速的下降(Tg = 165 oC)，为了解决热稳定性不足的问题，於是我们希望藉由无机材料的导入，藉此提升材料的热稳定性，首先实验利用无机矽氧烷Phenyltriethoxysilane 与侧链型二次非线性光学材料经由溶胶-凝胶反应形成半网状互穿型的高分子，当导入50 wt%的无机材料时，其Tg 提升至184 oC，但导入大量的无机成分，相对的降低了发色团基的比例(13.6 wt%)，因此光电系数值明显的下降(r33 = 5.2 pm/V)，造成热稳定性与光电性质无法兼得的窘境。
