We have prepared four new octaaminoamide resorcin[4]-arenes having hydrocarbon chains of different lengths (1, 2: R = CH 3 ; 3, 4: R = C 11 H 23 ) and different terminal groups (1, 3: NH 2 ; 2, 4: NMe 2 ). The surface tension and self-assembly of aqueous solutions of 2−4 were studied and their critical micelle concentrations (CMC) were determined. At the water/ air interface, compound 2 forms a multilayer structure, whereas compound 3 forms a bilayer and compound 4 a monolayer structure. In addition, we found that compound 3
