Abstract

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

wherein R¹ 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.

Claims

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

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
