Some physicochem. properties were studied for a synthetic amphiphile having 2 azacrown ether groups as polar heads (joined to both ends of a C16 alkyl chain) were studied. According to self-diffusion, viscosity, and surface tension trends (as well as the phase diagram), such an α-ω compd. forms large aggregates (presumably vesicles) and exhibits consolute phenomena. Its behavior can be considered intermediate between that of vesicle-forming lipids and that of nonionic surfactants.
