Keywords： α-cyanostilbene , optical properties , thermal stabilities , liquid crystal , smectic phase

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.
