摘要 本篇論文主要是在合成出具有氫鍵液晶性質的複合材料，合成過程是利用我們實驗室已發展出3,4-雙苯基順丁烯二醯亞胺(3,4-diphenylmaleimide)系列的化合物，再根據氫受體與氫給體之鍵結理論合成出2,4-雙胺基三口井(2,4-diaminotriazine)系列的化合物。為了探討3,4-雙苯基順丁烯二醯亞胺系列與2,4-雙胺基三口井系列的化合物是否能生成具有氫鍵液晶性質的複合材料，我們在合成上設計出不同碳鏈數的烷氧側鏈基，期待這樣的氫鍵複合物會有液晶的性質，再藉由熱重量分析儀(TGA)、微差熱掃描卡計(DSC)、紅外線光譜儀(FT-IR)及粉末X-射線繞射儀(XRD)探討其物性，合成出的複合物示意圖如下所示： Abstract The aim of thesis is to synthesize the hydrogen bonded liquid crystal complexes. Based on the recent development of derivatives of 3,4-diphenylmaleimide in our laboratory and the principle of “H-bonding donor and acceptor”, we successfully synthesized a series of 2,4-diaminotriazine. Sequentially, we add different lateral lengths of alkoxy groups onto both series of 3,4-diphenylmaleimide and 2,4-diaminotriazine to explore the hydrogen bonded liquid crystal complexes. These complexes have been characterized by themogravimetric analyzer (TGA), differential scanning calorimeter (DSC), Fourier transform infrared spectrum (FT-IR) and powder X-ray diffraction (XRD).
