Disclosed are a novel ionic organic compound and a method for producing the ionic organic compound by a simple process. Also disclosed are a hydrogelling agent composed of an ionic organic compound obtained by the method, an alcohol gelling agent, a gel which uses the gelling agent, while using water or methanol as a medium, and a carbon nanotube dispersant composed of the compound. Specifically disclosed is an ionic organic compound, represented by general formula (1). The compound is obtained by a condensation reaction of (A) an aromatic diamide compound or cyclohexane diamide compound having a 4-(chloromethyl)benzamide group at both ends, and (B) a compound selected from N,N,N',N'-tetramethylalkylenediamines which may have a substituent wherein there are 1-6 carbon atoms between nitrogen atoms. The thus-obtained ionic organic compound serves as a gelling agent which is capable of gelling a neutral aqueous solution or an alcohol. The solvent solubility can be changed by substituting the anion of the thus-obtained ionic compound with another anion by anion-exchange. (In the formula, A represents a linking moiety having one or more optionally substituted aromatic rings or a linking moiety composed of a cyclohexane ring; B represents a cationic functional group having a quaternized nitrogen atom, which is selected trom N,N,N',N'-tetramethylalkylenediamines which may have a substituent wherein there are 1-6 carbon atoms between nitrogen atoms; X represents a monovalent anion; and n represents an integer of 1-800.)
