A quantitative model that describes the assembly of diketopyrrolopyrrole-based donors and a perylenediimide acceptor into chiral superstructures, as a result of both hydrogen bonding and π•••π stacking. This model provides thermodynamic parameters (ΔH° and ΔS°) for all noncovalent interactions involved in the assembly and explains the subtle supramolecular cues that convert disordered aggregates into well-defined helical assemblies.
