Abstract
Three series of fluorinated phenyl 4‐[(4‐n‐alkoxy‐2,3‐difluorophenyl)ethynyl]benzoate liquid crystals have been synthesized. Their phase transition temperatures were measured by texture observation in a polarizing microscope and confirmed by DSC. Their mesomorphic properties and fluoro‐substituent effects were studied in detail.
