Abstract:

The incorporation of isoxazolinic ring into the mesogenic core is the great opportunity to evaluate the influence of some parameters related with liquid crystal (LC) properties. Due to the deviation from linearity, the use of these rings contributes to the studies of the understanding of steric and electronic influence related to molecular structure that will influence the mesomorphic properties. In this communication we are reporting the preparation and thermal analysis of three series of LC based on 3,5- disubstituted isoxazolines with different numbers of methylene carbons between the heterocyclic ring and the ester group.
