Abstract

Supramolecular chemistry is an attractive tool to tune the optoelectronic properties of semiconducting compounds and their morphology in organic electronics devices. The main noncovalent interactions in these compounds are π-π stacking and hydrogen-bonding is still scarce. However, it has been demonstrated that the incorporation of H-bonds into semiconductors resulted in more efficient devices than the parent molecules bearing no H-bonding groups. Nevertheless, there is no consensus regarding the impact of such interactions since no comparative studies have been performed. For this reason, the aim of this PhD is to study the influence of H-bonding on the self-assembly and optoelectronic properties of model small molecule semiconductors havi...
