Abstract
Synthesis of new derivatives of heterocyclic compounds such as (Triazoles, tetrazole, oxazole
and thiadiazole). Liquid crystalline complexes have been obtained from binary mixtures of
(4-pyridyl) heterocyclic derivatives with benzoic acid, 4-heptyloxychlorobenzoic acid or
4-octyloxybenzoic acid. The (4-pyridyl) heterocyclic derivatives are not mesomorphic, but the
H-bonded complexes are showed droplets nematic texture which is developed from threaded
nematic on slow heating. Their liquid crystalline properties were investigated by polarizing optical
microscopy.
