Nematic Liquid Crystals Containing Pyridine and Benzazole Rings

The liquid crystalline 6-alkoxynicotinic acids were prepared, and their transition temperatures measured. The isomeric 5-alkoxypicolinic acids are not mesomorphic. A series of 2, 6- and 2,5-disubstituted benzazoles were also synthesized. The effects of a molecule geometry, central linkages and a het...

Zusammenfassung:The liquid crystalline 6-alkoxynicotinic acids were prepared, and their transition temperatures measured. The isomeric 5-alkoxypicolinic acids are not mesomorphic. A series of 2, 6- and 2,5-disubstituted benzazoles were also synthesized. The effects of a molecule geometry, central linkages and a heteroatom on the mesomorphic properties of these compounds are discussed.
