| 摘 要： | 合成了液晶化合物α-氰基二苯乙烯衍生物(Z)-2-(4-十二烷基氨基苯基)-3-(4-十二烷氧基苯基)丙烯腈（T3），化合物T3与其同系物(Z)-2-(4-氨基苯基)-3-(4-十二烷氧基苯基)丙烯腈（T2）的浓溶液和固体态在蓝绿光波段均有强的荧光发射。 热重分析数据表明，两个化合物均有好的热稳定性。 利用差式扫描量热分析和偏光显微镜研究了化合物T3的液晶性质，同时借助粉末XRD分析化合物T3的分子间排列方式，表明化合物T3形成近晶相液晶。

| Abstract: | Liquid-crystal molecule with α-cyanostilbene as the core structure, (Z)-2-(4-(dodecylamino)phenyl)-3-(4-(dodecyloxy)phenyl)acrylonitrile(T3), was synthesized. Compound T3 and its analogue (Z)-2-(4-aminophenyl)-3-(4-(dodecyloxy)phenyl)-acrylonitrile(T2) exhibit strong fluorescence both in concentrated solutions and in solid state at blue-green bands. Thermogravimetric analysis for both compounds demonstrates the good thermal stability. Differential scanning calorimetry(DSC) and polarising optical microscope(POM) were used to study the liquid crystal property of compound T3. Molecular arrangement of compound T3 was studied by powder X-ray diffraction. The results indicate the formation of a smectic liquid crystal by compound T3. |
