Original Abstract
Novel ethyladamantylsolubilization side groups were found to induce pi-pi interactions between the conjugated cores through adamantyl–adamantyl stacking in soluble diketopyrrolopyrrole (DPP) derivatives. The closeness of the DPP cores amplifies charge transfer in the material,as far as pi-pi interaction is a dominant charge-hopping pathway. As a result, tenfold enhancement of hole mobilities exceeding those obtained for insoluble derivativeswasreached. Moreover, due to high crystallinity and co-planarity of the conjugated cores, electron transfer was preserved with a mobility of 0.2 cm2/(Vs)for dithiophene-DPP. At the same time, the material remained soluble, which is a significant advantage for purification and processing. This approach can be universally applied for many types of semiconducting organic materials containingtheimide motive, where solubilization is achieved by side-group substitution. Adamantane substitutions: a path to high-performing, soluble, versatile and sustainable organic semiconducting materials.
