-
, (2008/06/13)
Compounds of the formula I wherein R1 and R2 are each alkyl with 1-15 C atoms, and wherein one or two non-adjacent CH2 groups can also be replaced by --O--, --S--, --CO--, --O--CO--, --CO--O--, --CO--S--, --S--CO--, --CHHalogen--, --CHCN-- and/or --CH=CH--, A1 is 1,4-phenylene, trans-1,4-cyclohexylene or a single bond and A2 is STR1 in which Z is --O--CO--, --CO--O--, --S--CO--, --CO--S--, CH2 O--, --OCH2 -- or --CH2 CH2 --, with the proviso that, if A1 is a single bond, A2 is STR2 are suitable as components of chirally tilted smectic liquid crystal phases.
