all the compounds, compounds with flexible spacer (n = 4, 5, 6) exhibited excellent liquid crystalline nature. Structure–property relationships, the influence of different flexible spacers, the mesophase ranges and the photo-isomerization of liquid crystalline compounds were studied. The photophysical behavior was gained by UV–visible spectroscopy and optical properties were determined with a spectroscopic
通过偶氮染料(E)-4-(萘-2-基二氮烯基) 苯酚分别与各种 α, ω-二溴烷烃进行醚化反应,合成了一系列新的同系介晶溴烷氧基封端萘基衍生物,其中包含柔性间隔基以及偶氮和醚键。目前工作中的化合物具有通过各种光谱技术证实的各自正确的结构。研究了化合物的热致性质。在所有化合物中,具有柔性间隔基的化合物(n = 4, 5, 6) 表现出优异的液晶性质。研究了液晶化合物的结构-性能关系、不同柔性间隔基的影响、中间相范围和光异构化。通过紫外-可见光谱获得光物理行为,并通过椭圆偏振光谱仪测定光学特性。对所有分子结构进行了计算研究,并对介晶和光学特性进行了令人满意的解释。值得注意的是,合成的介晶材料是优异的电介质,使其适合电子和工业应用,并且具有合适的折射率,使其适合光导现象。
