Inducing the Formation of Functional Macroscopic Assemblies Through Programmed Orthogonal Supramolecular Interactions

Abstract

We studied the assembly of a system composed of diketopyrrolopyrrole (DPP) donors with chiral and achiral side chains that can form triple Hydrogen-bonds with perylene diimide (PDI) acceptors to form hierarchical superstructures. The homoaggregation of the individual components as well as heteroaggregate formation, as a result of Pi Pi stacking and H-bonding, were studied by variable temperature UV/Vis and CD spectroscopies and electronic structure theory calculations. It was found that, upon cooling, the achiral PDIs bind to disordered DPP stacks, which drives the formation of chiral superstructures. A new thermodynamic model was developed to describe quantitatively this novel assembly process.
