Adsorption experiments of organic dyes were performed using supramolecular hydrogels of an amphiphilic tris‐urea derivative. Cationic organic dyes were adsorbed efficiently; indeed, the adsorption of methylene blue was as high as 4.19 mol equivalents relative to the gelator. Two luminescence peaks were observed in the rhodamine 6G‐adsorbed supramolecular hydrogels, and their ratios varied with the amount of dye adsorbed. The results suggest that the adsorption proceeded gradually, that is, occurring initially on the fibers and later in the aqueous spaces of the supramolecular hydrogels.
