Abstract: | Fused, extended π‐systems such as larger acenes and heteroacenes are interesting compounds for organic thin‐film transistors (TFTs). The larger the number of linearly cata‐fused rings, the lower the stability of the acenes. By peri‐fusion of additional rings, the stabilities can significantly be increased. Here we present a facile approach to use a diborylated dihydroanthracene as precursor to get diareno‐fused perylenes in just two steps in high yields. The compounds show pronounced packing in the crystalline states by π‐stacking. Promising candidates have been used to fabricate p‐channel TFTs by vacuum sublimation showing field‐effect mobilities up to 0.12 cm2 V?1 s?1. |
