A series of functionalized pentacene derivatives based on symmetric and asymmetric substitutions of the terminal rings are synthesized (see figure). Field‐effect mobilities as high as 0.23 cm 2 V –1 s –1 are obtained with 2,3‐dibrompentacene. These devices show improved stability compared to pentacene and exhibit no significant decrease in mobility or on/off ratio when stored in air, with and without light exposure, even after three months.
