Molecular‐Curvature‐Induced Spontaneous Formation of Curved and Concentric Lamellae through Nucleation

Abstract Spontaneous formation of concentric lamellae was observed in self‐assembling giant surfactants consisting of a fluorinated polyhedral oligomeric silsesquioxane (FPOSS) head and flexible polymer tail(s). Owing to the asymmetrical sizes of the head and tail blocks and the rectangular molecular interface, the giant surfactants assumed a truncated‐wedge‐like molecular shape, which induced morphological curvature during self‐assembly, thus …
