Mesophase analysis, DFT calculation and microbial activity of a novel mesomorphic homologous series with ethyl 4-aminobenzoate

Abstract

A novel homologous series of cinnamoyl ester comprising of elven (C₁ to C₁₆) homologues liquid crystal (LC) samples have been synthesized and characterized using instrumental methods (spectral and thermal) of analysis and DFT approach. As results, middle ordered melting type of series with exhibition of nematic mesophase were observed. The observed mesogenic properties and transition temperature are affected by the size of alkyl chains that shows mesomorphism is susceptible to molecular structure. The prepared LCs of cinnamoyl ester derivatives were further examined for their biological activities and the obtained results indicates a good biological potential for the studied LC materials.
