| Abstract: | Ode series of phenyl cyclohexyl ethane liquid crystals are synthesized:m= 2, 3, 5n= 2, 3, 4, 5Seven compounds are synthesized by using simple synthetic method. Their structuresare determined by IR and NMR and five compounds show "emetic textures at the polarized microscopy. The phase transiton temperatures are measured by DSC. The influences of the terminal groups on the clearing points are discussed. |
