In 2004, oxadiazole based liquid crystals were shown to possess the elusive biaxial nematic at high temperatures. Our group has been successful in lowering the nematic onset temperatures in this class of compounds by incorporating lateral groups on the benzene rings. In order to further reduce the onset temperatures, we have prepared the less polar oxazole-based derivatives possessing a lateral halogen group (1). Synthetic details and phase behavior of these compounds will be discussed.
