Abstract

A dioxolane derivative represented by formula (G1) is provided. The explanation of the substituents is given in the specification. The use of the dioxolane derivative enables the production of a liquid crystal composition and a liquid crystal display device including the liquid crystal composition.

First claim

What is claimed is:

1. A compound represented by formula (G2):

wherein:
Ar 1 and Ar 2 independently represent hydrogen, a substituted or unsubstituted aryl group having 6 to 12 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 12 carbon atoms, or a substituted or unsubstituted cycloalkenyl group having 4 to 12 carbon atoms;
Ar 23 and Ar 24 independently represent a substituted or unsubstituted pyrenyl group;
a 1 and a 2 independently represent a substituted or unsubstituted alkylene group having 1 to 4 carbon atoms or a single bond; and
R 1 and R 2 independently represent hydrogen, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 6 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 12 carbon atoms.

2. The compound according to claim 1 ,
wherein:
Ar 1 and Ar 2 each represent hydrogen; and
a 1 and a 2 each represent a single bond.

3. The compound according to claim 1 ,
wherein the compound is optically active.

4. The compound according to claim 1 ,
wherein the compound is represented by formula (201):

5. A composition comprising:
the compound according to claim 1 ; and
a liquid crystal.

6. A liquid crystal display device comprising the composition according to claim 5 .

7. A compound represented by formula (G4):

wherein:
Ar 41 represents a substituted or unsubstituted arylene group having 6 to 12 carbon atoms;
n represents 2;
R 1 and R 2 independently represent hydrogen, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 6 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 12 carbon atoms;
R 3 represents hydrogen, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, or a substituted or unsubstituted alkoxy group having 1 to 6 carbon atoms.

8. The compound according to claim 7 ,
wherein R 3 represents a substituted or unsubstituted alkoxy group having 1 to 6 carbon atoms.

9. The compound according to claim 7 ,
wherein the compound is optically active.

10. The compound according to claim 7 ,
wherein the compound is represented by formula (300):

11. A composition comprising:
the compound according to claim 7 ; and
a liquid crystal.

12. A liquid crystal display device comprising the composition according to claim 11 .
