Abstract

A reactive perpendicular aligned organosilicon material is provided, having a general structural formula in the form of A-R, where A is —SiCl 3 and R represents a linear chained or a branched chained alkyl group with 5-20 carbon atoms. A CH 2 group in the alkyl group is substituted by a phenyl group, a naphthenic base, —CONH—, —COO—, —O—CO—, —S—, —CO—, or —CH═CH—, or an F atom or a Cl atom substitutes an H atom in the alkyl group. A Cl atom in the reactive perpendicular aligned organosilicon material and —OH on a surface of a substrate having no PI thereon form a hydrogen bond, leading to vertical arrangement of liquid crystal molecules between two opposite substrates.

First claim

What is claimed is:

1. A substrate;
and a liquid crystal mixture on the substrate, the liquid crystal mixture including a reactive perpendicular aligned organosilicon material, having a general structural formula that is A-R,
where A is —SiCl 3 ; and
R represents a linear chained or a branched chained alkyl group with 5-20 carbon atoms, wherein at least one of the CH 2 groups in the alkyl group is substituted by a phenyl group, a naphthenic base, —CONH—, —COO—, —O—CO—, —S—, —CO—, or —CH═CH—; or an F atom or a Cl atom substitutes at least one of the H atoms in the alkyl group;
wherein the reactive perpendicular aligned organosilicon material includes at least one of the following:

and wherein one of the Cl atoms of the —SiCl 3 group is hydrogen bonded with an —OH group on a surface of the substrate.
