"Cationic gemini surfactants complexed with anionic oligoglycine-aspartate (called gemini peptides hereafter) weresynthesized, and their aggregation behaviors were studied. The effects of the hydrophobic chain length (C10\u2212C22)and the length of the oligoglycine (0\u22124) were investigated, and it was clearly shown by critical micellar concentration,Krafft temperature, and isothermal surface pressure measurements that the hydrophobic effect and interpeptidic interactioninfluence the aggregation behavior in a cooperative manner. Below their Krafft temperatures, some of them formedboth hydro- and organogels with three-dimensional networks and the Fourier transform infrared measurements showthe presence of interpeptidic hydrogen bonds." .
