A silacyclohexane compound represented by the following general formula (I). ##STR1## In this formula, R denotes hydrogen, a linear-chain alkyl group with a carbon number of 1-10, a branched-chain alkyl group with a carbon number of 3-8, an alkoxyalkyl group with a carbon number of 2-7, a fluoroalkyl group with a carbon number of 1-10 in which one or two hydrogen atoms are substituted by florine atom(s), or an alkenyl group with a carbon number of 2-8. For the groups ##STR2## at least one of these is a trans-1-sila-1,4-cyclohexylene or trans-4-sila-1,4-cyclohexylene group whose silicon at position 1 or position 4 has a substitutional group(s) of H, F, Cl or CH 3 , and the other denotes a trans-1,4-cyclohexylene group. X denotes a CN, F, Cl, CF 3 , CF 2 Cl, CHFCl, OCF 3 , OCHF 2 , OCF 2 Cl, OCHFCl, R or OR group (R is the same as defined earlier). Y denotes H or F. Z denotes H or F. |
