Supramolecular structures generated by a p-tert-butylphenyl-amide derivative of cholic acid: From vesicles to molecular tubes

Abstract
The formation of supramolecular structures initiated by a p-tert-butyl-phenyl-amide derivative of cholic acid is investigated. The initial spherical vesicles, with a rather low effective bending constant, collapse into necklaces that self-transform into tubules of small diameter. Finally, molecular tubes are generated (see figure). During the process, the geometrical constraints of fixed surface area and fixed enclosed volume are obeyed.File in questo prodotto:
