They contain L-Asp linked by an amide bond both to n-hexyl chain on its C-side and an acyl chain linked to the N-side. Four different acylic residues are condensed to the N side. The newly synthesized compounds belong to two series of structures, as four of them contain L-Asp-b-benzyl ester, while the other four-a typical L-Asp-b-carboxylic group. The structures of the surfactants are categorized as pseudo-double alkyl chained amphiphiles, because one of the tails has a constant length of only six carbon atoms. Some of the newly synthesized surfactants are studied as monolayers on the air/water interface. The properties of the rest of them are determined by tensiometric and conductometric methods. Nano-and micro-sized supramolecular complexes of the compounds studied are observed in monolayers using Brewster Angle Microscopy (BAM) and Scanning Electron Microscopy (SEM) for samples after solvent evaporation.enArticle
