Hierarchical Self-Assembly of Amphiphilic Homopolymer into Unique Superstructures.

Supramolecular forces influence the morphologies of self-assemblies. Herein, self-assembled structures of an amphiphilic, norbornene-derived thiobarbiturate homopolymers () are discussed. The newly designed hompolymer shows self-assembled rod-like structures in tetrahydrofuran (THF) solvent. Formation of the rods are governed by hydrogen bonding motifs and amphiphilicity found in the molecular architecture. The solvent polarity controls their organization into cube-like and sphere-like structures at the next length scale. Encapsulation studies of hydrophobic magnetic particles as well as drug molecules into these superstructures demonstrate a novel route to fabricate multifunctional cube-like and sphere-like aggregates.
