Disclosed is a benzamide derivative represented by formula (1). In the formula, k1 represents an integer from 0-4, ml represents an integer from 1-100, and n1 represents an integer from 1-6. In addition, R1 represents a hydrocarbon group with 8-22 carbon atoms bonded via an oxygen atom; R2 represents H or a hydrocarbon group with 1-22 carbon atoms bonded via an oxygen atom; R3 represents H or a hydrocarbon group with 1-22 carbon atoms bonded via an oxygen atom; and R2 and R3 are not H at the same time.
The supramolecular organogelation of alcohols was observed in relatively hydrophobic amphiphiles with a short oligo(ethylene glycol) unit and three long alkylchains at room temperature, while the hydrogelation occurred in more hydrophilic gelators with a longer poly(ethylene glycol) unit and two long alkylchains at various temperatures. When a hot aqueous solution of some of the synthetic hydrogelators
