Local Structuring of Diketopyrrolopyrrole (DPP)-Based Semiconducting Polymers Using Molecular Dynamics Simulations
Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.

High performing organic semiconducting polymers show great potentials for use in electronic devices which is greatly dependent on the material crystallinity and packing. A series of short oligomers of the diketopyrrolopyrrole (DPP)-based materials that have shown to have high charge mobility are studied to understand the local structuring at atomic level for these materials. The simulations show that the tendency for this material class to form aggregates is driven by the interaction between DPP fragments, but this is modulated by the other conjugated fragments of the materials which afect the rigidity of the polymer and the ability to form aggregates of larger size.
