Synthesis of a new thermotropic liquid crystal monomer

Abstract

Liquid crystals phase is an intermediate phase of matter which is observed between crystalline solid phase and isotropic liquid phase in some substances. This research is focused on synthesizing and characterizing the structure of new thermotropic liquid crystal monomer. In this study, three precursors were used in order to synthesis liquid crystal structure which are A-Phenol (2,2-Bis (4-hydroxyphenyl) propane) as the mesogenic group, 3-chloro-1-propanol as the spacer linkage and allyl chloride as the polymer backbone. Spectroscopy and chromatography analysis were conducted for conformation of the product obtained. However, mass spectroscopy analysis revealed that the product obtained was not a liquid crystal monomer due to different m/z value.
