Abstract
The present invention provides organogermanium compounds and liquid crystal compositions comprising such a compound.
Claims27
A liquid crystal composition comprising at least two different compounds, wherein at least one of the compounds is an organogermanium compound.
A liquid crystal composition which is in a liquid crystal phase at room temperature, said liquid crystal composition comprising an organogermanium compound.
An enantiotropic liquid crystal composition comprising an organogermanium compound.
A compound of the formula:
- D-E-F;
- wherein
- D is a chain having from about 5 to about 20 chain atoms, wherein each of the chain atoms is independently selected from the group consisting of C, O, N, S, Ge, and Si;
- E is a core moiety having two, three, or four ring moieties, wherein each ring moiety is connected to the other ring moiety by a linker, and wherein each linker is independently comprised of from 0 to about 5 chain atoms;
- F is a chain having from about 5 to about 20 chain atoms, wherein at least one of the chain atoms is germanium and each of the remaining chain atoms is independently selected from the group consisting of C, O, N, S, and Si.
