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