Novel fluorinated ferroelectric organosiloxane liquid crystals

A progress report on the synthesis and characterisation of a series of fluorinated chiral bi-mesogen low molar mass organosiloxane materials is presented. The mesogenic moiety is identical to that in the TSiKN65F mono-mesogen material reported by Naciri et al., which displays a de Vries-type SmA* phase. The parameter varied across the series is the length of the alkyl chain linking the mesogen moiety to the siloxane. The material with 10 carbon atoms in the chains displays a stable smectic phase with ferroelectric response at room temperature, whereas the materials with 6, 7 and 8 carbon atoms tend to crystallize.

Ferroelectric liquid crystals for nonlinear optics applications

The present invention provides ferroelectric liquid crystal and liquid crystal compounds, among which are compounds which possess large X(2), i.e. second order nonlinear susceptibility and thus make them useful in optical and nonlinear optical applications. The invention includes chiral nonracemic compounds of formula STR1 where one of n or m is 1; k is 1 and B is COO or OOC; R' is a straight-chain or branched alkyl or monoalkene group having from 1 to 20 carbon atoms where one or more of the non-neighboring carbon atoms in R', except any unsaturated carbon atoms, can be replaced with O, S or a Si(CH3)2 group; and R' is a chiral nonracemic tail group selected from the group consisting of --O--C*H(CH3)Rc, --O--C*H(CH3)COORd and --O--CH2 C*HF--C*HF--R6 in which the * indicates an asymmetric carbon enriched in one stereoconfiguration which for --O--CH2 C*HF--C*HF--Re is either the (S,S) or (R,R) stereoconfiguration wherein: Rc is a straight-chain or branched alkyl or monoalkene group having 2 to 15 carbon atoms; Rd is a straight-chain or branched alkyl or monoalkene group having 2 to 13 carbon atoms and Re is a straight-chain or branched alkyl or monoalkene group having 2 to 11 carbon atoms wherein in Rc, Rd or Re one or more non-neighboring carbon atoms, except any unsaturated carbon atoms, can be substituted with an O, S, or Si(CH2)2 group.
