本實驗合成不同碳鏈長度的單官能性液晶單體4-butoxyphenyl- 4’-(6-acryloyloxyhexyloxy)benzoate、4-butoxyphenyl-4’-(3-acryloyloxy- propyloxy)benzoate、4-butoxyphenyl-4’-(11-acryloyloxyundecyloxy) benzoate、兩種雙官能性單體1,4-di-〔4-(6-acryloyloxyhexyloxy) benzoyloxy〕benzene與4,4’-bis(6-(acryloyloxy)hexyloxy)biphenyl，及含甲氧烷基之偶氮苯衍生物4-hexyloxy-4’-methoxy-azobenzene。所合成之化合物均使用FTIR、1H-NMR、EA、DSC等儀器來加以鑑定。實驗過程中，將液晶ZLI-2293與光學活性摻混物S811混和均勻，製作成膽固醇液晶薄膜，可調配出在可見光區域有選擇性光反射的光學薄膜；再分別添加入不同配方及比例的官能性單體，探討照光聚合後對膽固醇液晶主體選擇性光反射波段(△λ)移轉之影響。另外，亦於系統中添加不同的偶氮苯衍生物，其一具有旋光性，另一個則無；探討此二種偶氮苯衍生物在照光聚合前、後對系統選擇性光反射波段的影響。藉由照射紫外光與可見光之間的轉換，可得到不同的選擇性光反射波段。

　　A series of monofunctional liquid crystalline monomers of 4-butoxyphenyl-4’-(6-acryloyloxyhexyloxy)benzoate, 4-butoxyphenyl-4’ -(3-acryloyloxy-propyloxy)benzoate, 4-butoxyphenyl-4’-(11-acryloyloxy undecyloxy)benzoate with various spacer lengths, two kinds of difunctional monomers of 1,4-di-〔4-(6-acryloyloxyhexyloxy) benzoyloxy〕benzene and 4,4’-bis(6-(acryloyloxy)hexyloxy)biphenyl, and photoisomerizable 4-hexyloxy-4’-methoxy-azobenzene were synthesized. Compounds synthesized in this investigation were confirmed using FTIR, 1H-NMR, DSC, and EA. Cholesteric liquid crystal cells were fabricated using commercially available ZLI-2293/S811 cholesteric liquid crystals and synthesized functional monomers. Effects of chiral and achiral monomers on the reflected band, light　transmittance, stability, and reliability of the cholesteric liquid crystal cells were investigated in detail. Azobenzene derivatives were found to affect the optical properties of the cholesteric liquid crystal cells. Optical textures of the prepared cholesteric liquid crystals and morphologies of polymer matrixes were all investigated.
