Hydrogen-Bonded Organic Semiconductors with Long Charge Carrier Lifetimes

Hydrogen bonds are noncovalent interactions able to improve the electronic properties of self-assembled semiconductors. Nevertheless, it is necessary control parameters influencing formation hydrogen achieve hierarchical structures with enhanced properties. In this work, we explore two hydrogen-bonded thiophene-capped diketopyrrolopyrrole (DPP) derivatives containing amides different topology (C- or N-centered) and compare them a analogue without bonds. We demonstrate differences in optoelectronic self-assembly amide-containing DPP derivatives, as well their charge carrier lifetimes. prove superior comparison molecule bonds, show that our molecular design strategy results supramolecular particularly long lifetimes compared other semiconductors reported literature.
