title: Palladium- or proton-induced submicro spherical aggregation of macrocyclic amphiphiles in aqueous solution.
abstract: Synthetic amphiphiles have been found to self-assemble into a variety of structures such as micelles, vesicles, cylinders and lamellae in aqueous media over many length scales. We report herein cation-induced aggregation of hexaaza-cyclophanes in water. Pd(2+)- or proton-induced formation of submicro spherical aggregates was observed by several spectroscopic and microscopic methods.
