Abstract
This invention relates to a liquid crystal composition and articles comprising the composition. The composition comprises at least one compound of each of the Formulas (I), (II) and (III), as defined herein. A process for making the composition is also provided.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A composition comprising at least one compound from the group of compounds represented by the structures of each of the following Formulas (I), (II) and (III),
wherein
Z is F, Cl, Br, I, —OTs, —OTf, —OMs, CN, or NO 2 ;
Y is H, F, Cl, Br, I, —OTs, —OTf, —OMs, CN, or NO 2 ;
with the proviso that Z is not equal to Y;
n1, n2, n3, n4, n5, and n6 are each independently integers 3 to 20;
m and p are each independently integers 0, 1, or 2;
A is a divalent radical selected from the group:
wherein R 3 through R 10 are each independently selected from the group: H, C 1 to C 8 straight or branched chain alkyl, C 1 to C 8 straight or branched chain alkyloxy, F, Cl, phenyl, —C(O)CH 3 , CN, and CF 3 ; X 2 is a divalent radical selected from the group: —O—, —(CH 3 ) 2 C—, and —(CF 3 ) 2 C—; and each B 1 and B 2 is a divalent radical independently selected from the group: R 11 -substituted-1,4-phenyl, wherein R 11 is H, —CH 3 or —OCH 3 , 2,6-naphthyl; and 4,4′-biphenyl; with the proviso that when m+p is equal to 3 or 4, at least two of B 1 and B 2 are R 11 -substituted-1,4-phenyl.
2 . The composition of claim 1 wherein the total amount of compounds of Formula (I) are present in the range of about 5 mole percent to about 95 mole percent based on the total content of the composition.
3 . The composition of claim 1 wherein the total amount of compounds of Formula (II) are present in the range of about 0.1 mole percent to about 50 mole percent based on the total content of the composition.
4 . The composition of claim 1 wherein the total amount of compounds of Formula (III) are present in the range of about 0.1 mole percent to about 90 mole percent based on the total content of the composition.
5 . The composition of claim 1 wherein for at least one compound of each of the Formulas (I), (II) and (III), m is 0 and p is 0.
6 . The composition of claim 1 wherein for at least one compound of each of the Formulas, m is 1 and p is 0.
7 . The composition of claim 1 wherein for at least one compound of each of the Formulas (I), (II) and (III), m is 1 and p is 1.
8 . The composition of claim 1 wherein for at least one compound of each of the Formulas (I), (II) and (III), m is 1 and p is 0; and wherein for at least one compound of each of the Formulas (I), (II) and (III), m is 1 and p is 1.
9 . The composition of claim 1 wherein n1 through n6 are each independently selected from the group consisting of 3 to 10.
10 . The composition of claim 1 wherein n1, n2, and n4 are the same.
11 . The composition of claim 1 wherein the composition comprises only one compound of Formula (I).
12 . The composition of claim 11 wherein n1, n2, and n4 are the same.
13 . The composition of claim 1 wherein Z is Br, I, —OTs, —OTf, or —OMs; and Y is H, Br, I, —OTs, —OTf, or —OMs.
14 . The composition of claim 13 wherein Z is Br and Y is H.
15 . A liquid crystal composition comprising the composition of claim 1 .
16 . The liquid crystal composition of claim 15 wherein Formula (I) is Formula (XXIII), as follows:
17 . The liquid crystal composition of claim 15 further comprising at least one chiral compound.
18 . An article comprising the liquid crystal composition of claim 15 .
19 . An article comprising the liquid crystal composition of claim 17 .
20 . The article of claim 18 which is fabricated as an optical element.
21 . The article of claim 19 which is fabricated as an optical element.Join the waitlist — get patent alerts
