Abstract
AbstractMaterials Synthesis and Processing Polycyclic aromatic hydrocarbon (PAH) diimides are indispensable candidates for n‐type organic semiconductors in organic optoelectronic devices. Developing new PAH diimide building blocks are of remarkable significance for material diversity and further advance in organic semiconductors. In this contribution, 4,5,8,9‐picene diimide (PiDI) was designed and synthesized. Controllable stepwise bromination of PiDI were accomplished to afford 13‐monobromo‐, 13,14‐dibromo‐, 2,13,14‐tribromo‐ and 2,11,13,14‐tetrabromo‐PiDI. Moreover, cyanation of 2,11,13,14‐tetrabromo‐PiDI gave the corresponding tetracyanated PiDI, which can be utilized as n‐type semiconductor with OFET electron mobility up 0.073 cm2 V−1 s−1. This result demonstrates the potential of PiDI as a building block for constructing new high‐performance electronic‐transporting materials.
