Progress on the Study of Liquid crystals Containing 1,3,4-Oxadiazole Unit

1,3,4-Oxadiazole derivatives have been widely applied as organic electron transport and emmiting materials because of their thermo and chemical stabilities and highly electron affinity.In this paper the recently progreess on the liquid crystals containing 1,3,4-oxadiazole units has been reviewed.Including the linear and star shaped LC containing 1,3,4-oxadiazole unit as well as oxadiazole unit contained polymers.Fucosed on the releationship among the strcutre and mesophase behavior and the elctrooptical properties of such LC.All the studies have shown that by combining the LC property with the electrooptical properties of 1,3,4-oxadiazole derivatives would be benefit to the much more widely application of such new materials.
