Competitive Self-Assembly Driven as a Route To Control the Morphology of Poly(Tannic Acid) Assemblies

Abstract

With an attempt to develop some supermolecular assembly of particular structure through a controllable method, the present study developed two distinct assembly pattern for Poly(Tannic Acid) (PTA) by means of adjusting the component and composition of a binary solvent system. The assembling mechanism was explored through the comparison of the theoretical calculation and experimental results with respect to how the solvent sets affect the nature of the intermolecular interactions among oligomers. The results indicate the morphology of the aggregation of PTA is determined by the nature of the intermolecular interactions among oligomers. While the cuboid shaped aggregation is likely the results of π-π stacking self-assembly, the sphere shaped morphology is formed through intermolecular hydrogen bonding among the oligomers. The results of the present work provide valuable resources to tune the aggregation morphology by quantitatively adjusting the physical properties of the binary solvent.
