ABSTRACT
A new homologous series, 2-formyl-4-((E)-phenyldiazenyl)phenyl)diazinyl)phenyl (E)-(3)-(4 alkyloxyphenyl)acrylate is synthesized with a view to understand and establish the relation between mesogenic properties and structure of molecules. The mesophase behaviour of the liniyer-shaped molecular system core with azo-ester linker (E1–E9) was examined in relation to the impacts of alkoxy side groups on three distinct terminal positions. POM and DSC analyses were used to verify the synthetic derivatives’ mesogenic behaviour and thermal stability. These compounds based on azo-esters exhibited mesomorphic characteristics of the smectic C. Fan, broken fan, schlieren, and threaded type were the textural patterns of the synthesised chemicals that were observed. At lower temperatures, all derivatives displayed a further stabilised mesophase and a good temperature range. To learn more about how varied side-chains affect liquid crystalline characteristics, the structure-property link was further investigated.
