Assembly effect on the charge carrier mobility in quaterthiophene-based n/p-materials

Abstract

Precise control of supramolecular polymerization by tuning the pH value of a peptide-based quaterthiophene donor moiety allows obtaining three different aggregates. Charge screening of the assemblies with different electron acceptor units steers the formation of n/p-co-assembled materials with appealing optoelectronic properties. We have demonstrated that control on the organization of the main building blocks drastically affects the conductivity properties of the mixed n/p-co-assemblies.
