A series of phase-selective gelators (3a-3e) was synthesized and characterized by ¹H and ¹³C nuclear magnetic resonance spectroscopy and mass spectroscopy. The phase-selective activity assay was carried out in organic solvent and water mixture system and the results showed that compound 3c possessed high gelling abilities in the powder form for the removal of benzene, toluene, xylenes and petrol from their biphasic mixtures with water via a shaking process at room temperature. In addition, the efficient purification of toxic dye solutions has been realized by using 3d-benzyl alcohol gel as the adsorbent. Ultraviolet-visible spectroscopy provides the quantification means for the estimation of the purification efficacy. The simple operation and high removal efficiency of the organic solvents from water indicate the promising applicability of these dipeptide gelators in water purification.
