Abstract

A novel liquid-crystalline ionic conductor, which is useful in the electric, electronic, chemical and bioengineering fields, as an anisotropic reaction solvent, ionic conductor, electric field-responsible conductor or the like, and a method for producing the same, is provided. The liquid-crystalline ionic conductor is obtained by mixing an organic molten salt with a-liquid-crystalline organic molecule or a liquid-crystalline inorganic molecule, which comprises a moiety miscible to the organic molten salt and a moiety that shows liquid-crystalline orientation, thereby forming a liquid-crystalline ionic conductor, wherein the organic molten salt is assembled to the liquid-crystalline molecule.

Claims

1. A liquid-crystalline ionic conductor, comprising an organic molten salt and a liquid-crystalline molecule, which are mixed and assembled to form a smectic structure.

2. The liquid-crystalline ionic conductor of claim 1, wherein the organic molten salt is assembled between layers of the liquid-crystalline molecules.

3. The liquid-crystalline ionic conductor of claim 1, which is in the form of a cell or an oriented cell.

4. The liquid-crystalline ionic conductor of claim 1, wherein the liquid-crystalline molecule comprises a moiety that is miscible to the organic molten salt and a moiety that shows liquid-crystalline orientation.

5. A method for producing a liquid-crystalline ionic conductor which comprises mixing an organic molten salt with a liquid-crystalline molecule, wherein the liquid-crystalline molecule forms a smectic structure.

6. A liquid-crystalline ionic conductor, comprising an organic molten salt and a liquid-crystalline molecule, which are mixed and assembled to form a columnar structure or a cubic structure.

8. The liquid-crystalline ionic conductor of claim 6, wherein the organic molten salt is assembled between layers of the liquid-crystalline molecules.

9. The liquid-crystalline ionic conductor of claim 6, which is in the form of a cell or an oriented cell.

7. A method for producing a liquid-crystalline ionic conductor which comprises mixing an organic molten salt with a liquid-crystalline molecule, wherein the liquid-crystalline molecule forms a columnar structure or a cubic structure.
