Some series of trans-1-(4-substituted phenyl)-2(trans-4-n-alkylcyclohexyl) ethylenes, which show nematic phases, were prepared. Their transition temperatures, birefringences and bulk viscosities were measured. Their properties are compared with those of other nematic cyclohexanes: phenyl cyclohexane carboxylates, phenyl thiol cyclohexane carboxylates and phenyl cyclohexanes. The phenyl cyclohexyl ethylenes have wide nematic ranges with high clearing points and have high birefringences. Their photochemical stabilities were tested. 10 refs.
