1D vs. 2D shape selectivity in the crystallization-driven self-assembly of polylactide block copolymers

Assemblies of polylactide-based amphiphiles in alcohols are shown to give unprecedented shape selectivity based on unimer solubility, leading to the formation of large uniform 2D diamond-shaped platelets, up to several microns in size.

The fabrication of a supra-amphiphile for dissipative self-assembly

Dissipative self-assembly is a challenging but attractive field of supramolecular science, because it generally concerns complex system but is more close to the self-assembly of living bodies. We successfully realized dissipative self-assembly by coupling a supra-amphiphile with a chemical oscillator.
