THE PREPARATION AND LIQUID CRYSTALLINE PROPERTIESOF SOME HOMOLOGUES SERIES OF 1, 2, 4-OXADIAZOLEDERIVATIVES

Abstract

Homologues series of some derivatives of 3, 5-(4-substituted phenyl)-l, 2, 4-
oxadiazole were synthesized and their phase behavior was studied. Introduction of
the pentagonal hetero aromatic ring leads to significant changes in mesomorphic
behavior. The synthesized compounds exhibit nematic phase.
