摘要：
A silacyclohexane compound of the following formula (I) ##STR1## wherein R represents an organic residue; at least one of ##STR2## represents a substituted or unsubstituted trans-1-sila-1,4-cyclohexylene group or trans-4-sila-1,4-cyclohexylene group and the other represents a trans-1,4-cyclohexylene group, L.sub.1 and L.sub.2 independently represent H, F, Cl or CH.sub.3 ; X represents an organic residue or CN, F, Cl; and m and n are, respectively, 0 or 1 provided that m+n=1. Silacyclohexane compounds are useful in liquid crystal compositions and also in liquid crystal devices.
