| Abstract: | New liquid crystals of 3HEHV ((4-trans-propyl-cyclohexyl-1), (4?-vinyl-cyclohexyl-1?)-ethane-1,2) and 3HB2V ((4-trans-propyl-cyclohexyl-1), (4-butenyl-3,4)-benzene) were synthesised and evaluated as the diluents for medium birefringence liquid crystal mixtures. The procedures transferring cis-isomers into trans-isomers of the cyclohexane were described. The results showed that both 3HEHV and 3HB2V decrease the crystallisation temperature and the viscosities by doping them with the medium birefringence mixtures in a fraction of 15%. The characteristics of the structures are correlated with the properties of the mixtures. |
