Liquid Crystalline Oxadiazole with Electron Transporting Capability

In a thin film of an oxadiazole-based liquid crystal, 2,5-bis(4-octadecyloxybenzilidene-4-aminophenyl)-1,3,4-oxadiazole 1, fairly high electron mobility enhanced by molecular orientation was observed; electron mobility in the glassy liquid crystalline film of oxadiazole 1 was 3.6 × 10−5cm2V−1s−1 at an electric field of 2 × 105 Vcm−1 at room temperature, and the value was about ten times that in the isotropic glassy film of oxadiazole 1.
