Synthesis and characterization of new mesogenic oximes

摘要

Synthesis of a-homologous series of mesogenic 4-(n-alkoxy)benzaldehyde oximes starting from 4-hydroxybenzaldehyde with n-alkyl bromide under phase transfer condition is described. Optical texture studies have been carried out using Leitz polarizing microscope and it is found that the synthesized compounds exhibit Smectic B, Smectic I and Smectic H phase.
