AB Organic materials have proven to be efficient active materials in electronics, being possiblealternatives to inorganic semiconductors in electronic devices, such as organic field effects transistors(OFETs) or organic solar cells. The versatility of organic synthesis allows us to endow small moleculesor polymers with the desired optoelectronic properties. However, the final efficiency of a given deviceis not only based on the molecular design but also on the way the molecules assemble. In this sense,non-covalent interactions play a crucial role as they are able to control the supramolecular assembly.Hydrogen-bonding has been proven a promising strategy to improve the film morphology in organicelectronic devices with semiconductors able to efficiently transport charges. In this project, twocompounds have been studied, based on a straightforward diketopyrrolopyrrole (DPP) with athiophene-capped as the electroactive component and amide groups serving as the hydrogen-bondingunits1. Theamide groups are positioned with two different topologies, C-centered (C-1) or N-centered(N-1) which are five carbons apart from the lactam rings of the DPP. We have compared these materialswith the control derivative, 1, whose structure lack amide groups (Figure 1). Finally, the potential ofthese semicondcutors as active components in organic electronics have been tested in organic fieldeffects transistors (OFETs).
