Two novel series of bent-core liquid crystals (9a similar to 9e and 10a similar to 10e) were prepared with a central bent core based on 2,5-disubstitueted-1,3,4-oxadiazole, ester group bridge (coo), alkyl tails with different carbon numbers (n=5 similar to 9), and one side wing substituted by fluorine atom. The structures of the target compounds were confirmed by IR, H-1 NMR, C-13 NMR, MS, and their transition temperatures and phase textures were investigated by using differential scanning calorimetric (DSC) and polarizing optical microscopy (POM). The result suggested that all target compound...
