Abstract

With an attempt to develop some supermolecular assemblies of a particular structure through a controllable method, the present study developed two distinct assembly patterns for Poly(Tannic Acid) (PTA) by means of adjusting the components and composition of a binary solvent system. The assembly mechanism was explored through the comparison of theoretical calculations and experimental results with respect to how solvent sets affect the nature of intermolecular interactions among oligomers. The results indicate that the morphology of the aggregates of PTA is determined from the nature of the intermolecular interactions among oligomers. While a cuboid shaped aggregate is likely the result of π-π stacking self-assembly, a 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.
