New Low‐Molecular‐Mass Gelators Based on L‐Lysine: Amphiphilic Gelators and Water‐Soluble Organogelators

The new L ‐lysine alkali‐metal salts 1 – 5 (M⁺=Na⁺ and K⁺) with different alkyl groups at the N^α‐position were easily synthesized, and their hydro‐ and organogelation properties were investigated. All compounds were H₂O‐soluble, and some salts, especially the potassium salts, functioned as a hydrogenator that could gel water below 2 wt‐%. These salts also had organogelation abilities for many organic solvents.
