Generation dependent mesophase behavior in extended amphiphilic dendrons in the shape of macromolecular dumbbells

Small angle X-ray scattering studies of 2nd and 3rd generation based extended amphiphilic dendrons in the shape of macromolecular dumbbells with identical hydrophilic volume fractions suggest 2-D hexagonal columnar and Pm3n micellar cubic mesophases, respectively, elucidating the role of shape induced interface curvature in mesophase formation.
