Patent ID: 7470376

Claim:
A material composition comprising an enantiomeric excess of one enantiomer of a compound wherein: A and C are the same and selected from one of CH 2 , —O—, and —C(R1)(R2)-; B and D are the same, but independent of A and C, and are selected from one of CH 2 , —O—, and C(R1)(R2); wherein R1 and R2 are independently selected from a C 1 -C 5 alkyl group and C 1 -C 5 alkoxy group and optionally wherein if R1 and R2 groups are on the same ring, they can form a fused ring; X is each independently selected from one of one or more H atoms and a halogen; Z is selected from one of an H atom, halogen, CN, straight, chain, branched alkyl, alkoxyl, and nitrogen based substituent groups; RNG1 and RNG2 are each independently selected from one of 1,4-phenylene in which, one or more CH groups may be replaced by N, 1,4-cyclohexylene in which, one or two non-adjacent CH2 groups may be replaced by O and/or S, 1,4-cyclohexenylene, 1,4-bicyclo(2,2,2)octylene, piperidine-1,4-diyl, naphthalene-2,6-diyl, decahydronaphthalene-2,6-diyl, 1,2,3,4-tetrahydronaphthalene-2,6-diyl, and mono- or poly-substituted derivatives of such compounds substituted with halogen, cyano or nitro groups, or alkyl, alkoxy or alkanoyl groups having 1 to 12 C atoms wherein one or more H atoms may be substituted by an F or Cl; n represents an integer independently varying from 0 to 3; m represents an integer independently varying from 0 to 2; p represents an integer independently varying from 1 to 4; q represents an integer independently varying from 0 to 5; and Q each independently represents a carbon C—Rc, or nitrogen, wherein Rc is independently hydrogen or any substituent.
