Abstract: The invention provides a method for manufacturing a polysiloxane resin with charge transporting properties by uniformly bonding charge transporting groups in effective concentration within a polysiloxane resin. The charge transporting groups are formed in the resin by cohydrolyzing and condensing silane monomers with an aromatically substituted tertiary amine which has been modified by substitution of one or more of the aromatic rings with a hydrocarbon group containing a silyl group bearing hydrolyzable substituents. Tertiary amines have ionization potentials of 4.5 to 6.2 volts.

Abstract: A liquid crystal device wherein the liquid crystal material is a siloxane-containing compound characterised by the the general formula ##STR1## wherein R is a C.sub.1-10 alkyl or ##STR2## each R' is a C.sub.1-4 alkyl, T is ##STR3## X is an alkyl or halogen-substituted alkyl group having at least one chiral center, Y is F, m is 0, 1 or 2 and n is 10, 11 or 12. Also claimed is a device wherein the liquid crystal material is disposed between a pair of substrates.
