Abstract
Compounds useful as components of LC and FLC compositions which in turn are useful in the manufacture of optical devices. Compounds of this invention have a silane tail, which can contain more than one Si. Compounds of this invention can include those with disilane tails. The invention provides LC compositions containing one or more of the silanes of this invention. Addition of one or more of the compounds of this invention to LC compositions can result in significant improvement in optical or LC properties. In particular, the compounds of this invention can significantly lower the melting point, freezing point or both of an LC composition resulting in significant improvement in device stability.
