Abstract

There is provided a novel gelator containing a monourea derivative. A gelator comprising a compound of formula (1):

wherein R 1 is a linear or branched alkyl group having a carbon atom number of 2 to 20, a cyclic alkyl group having a carbon atom number of 3 to 20, or a linear or branched alkenyl group having a carbon atom number of 12 to 20; and Ar is a C 6-18 aryl group unsubstituted or optionally substituted with at least one substituent selected from the group consisting of a C 1-10 alkyl group, a C 1-10 alkoxy group, a C 6-18 aryloxy group, a halogen atom, a nitro group, a phenyl group, a C 2-10 alkylcarbonyl group, and a C 7-18 aralkyl group.

First claim

The invention claimed is:

1. A gelator comprising a compound of formula (1):

wherein
R 1 is a linear alkyl group having a carbon atom number of 14 to 20; and
Ar is a phenyl group substituted with a benzyl group.

2. A gel comprising the gelator according to claim 1 , and a hydrophobic organic solvent, a hydrophilic organic solvent, a hydrophilic organic solution, or an ionic liquid.

3. The gel according to claim 2 , wherein the hydrophobic organic solvent is at least one selected from the group consisting of a vegetable oil, an ester, a silicone oil, and a hydrocarbon.

4. The gel according to claim 2 , wherein the hydrophilic organic solvent is at least one selected from the group consisting of methanol, ethanol, 2-propanol, i-butanol, pentanol, hexanol, 1-octanol, isooctanol, acetone, cyclohexanone, acetonitrile, dioxane, glycerol, butanediol, propylene glycol, ethylene glycol, and dimethylsulfoxide.

5. The gel according to claim 2 , wherein
the hydrophilic organic solution is a mixed solvent of a hydrophilic organic solvent and water, and
the hydrophilic organic solvent is at least one selected from the group consisting of methanol, ethanol, 2-propanol, i-butanol, pentanol, hexanol, 1-octanol, isooctanol, acetone, cyclohexanone, acetonitrile, dioxane, glycerol, butanediol, propylene glycol, ethylene glycol, and dimethylsulfoxide.

6. The gel according to claim 2 , wherein the ionic liquid comprises a combination of a cationic species selected from the group consisting of imidazolium, pyridinium, piperidinium, pyrrolidinium, phosphonium, ammonium, and sulfonium, and an anionic species selected from the group consisting of a halogen, a carboxylate, a sulfate, a sulfonate, a thiocyanate, a nitrate, an aluminate, a borate, a phosphate, an amide, an antimonate, an imide, and a methide.
