Abstract

The construction of a λ-shaped three side substituted alkoxy based molecular system (E1-E8) with azo-ester group was carried out and studied for liquid crystalline applications. The mesogenic behaviour and thermal stability of synthesized derivatives were checked and analyzed by POM, DSC and TGA analysis. These azo-ester based compounds show smectic C and nematic type mesomorphic properties. The observed texture patterns of the synthesized compounds are fan, broken fan, schlieren and threaded types. All derivatives shows broad temperature range of mesophase and further stabilized upto the room temperature. The structure-property relationship has been further studied to understand the effect of variable side-chain on liquid crystalline properties.

λ型偶氮液晶的合成与表征:末端烷氧基的影响

本文研究了偶氮酯基λ型三侧取代烷氧基分子体系(E1-E8)在液晶中的应用。通过POM、DSC和TGA分析对合成衍生物的介生行为和热稳定性进行了检验和分析。这些偶氮酯基化合物具有近晶C型和向列型的介形性质。观察到合成化合物的织构图案为扇形、破碎扇形、纹影和螺纹型。所有衍生物均表现出较宽的中间相温度范围，并在室温下进一步稳定。进一步研究了结构-性能关系，以了解可变侧链对液晶性能的影响。
