摘要：

Novel ethyladamantyl solubilization 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 the pi-pi interaction is a dominant charge-hopping pathway. As a result, tenfold enhancement of hole mobilities exceeding those obtained for insoluble derivatives was reached. Moreover, due to high crystallinity and co-planarity of the conjugated cores, electron transfer was preserved with a mobility of 0.2 cm(2) V-1 s(-1) 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 containing the imide motif, where solubilization is achieved by side-group substitution.
