Abstract
Cones are a very rare form of supramolecular self-assembly. It is shown that mixing of an unsymmetrical bola-fatty acid and a diamine (catanionic system) in dilute solutions can produce aggregates having a conical shape. These assemblies are made of frozen unsymmetrical monolayers in which bolas are arranged on a regular hexagonal lattice. Cones are stabilized by the introduction of pentagonal or n-gonal defects in the bola-lattice which yields the quantification of the cone apex angle according to the Euler theorems. The formation of cones represents a novel route for lipid and surfactant systems to minimize the edge energy of a flat membrane.Keywords
