The design and synthesis of high‐performance n‐type organic semiconductors are important for the development of future organic optoelectronics. Facile synthetic routes to reach the K‐region of pyrene and produce 4,5,9,10‐pyrene diimide (PyDI) derivatives are reported. The PyDI derivatives exhibited efficient electron transport properties, with the highest electron mobility of up to 3.08 cm2 V−1 s−1. The tert‐butyl‐substituted compounds (t‐PyDI) also showed good one‐ and two‐photon excited fluorescence properties. The PyDI derivatives are a new family of aromatic diimides that may exhibit both high electron mobility and good light‐emitting properties, thus making them excellent candidates for future optoelectronics. 相似文献
