New alk(en)-yl-terminated liquid crystal cpds. and use as achiral component - for stabilising smectic C phase in chiral tilted smectic medium used in LCD, esp. ferroelectric LCD

New liquid crystal (LC) cpds. are linear di- and tri-cyclic ester, ether or satd. or unsatd. hydrocarbon cpds. with terminal (alkoxy)alk-1-enyl gp(s)., of the formula R-(-CX=CY-) -(A1-Z1) -A2-Z2-(-CX=CY-) -R' (I): and R' = 1-15 C alkyl, opt. with halogen substit(s)., in which one or more n...
