The benchmark of soluble organic semiconductors based on acenes is the 6,13‐

bis(triisopropylsilylethynyl)pentacene (TIPS–PEN). However TIPS–PEN still suffers from photoinduced oxidation due to its low degree of aromaticity. Increasing the aromaticity while keeping similar optical and electrochemical properties as well as a shape suitable for good hole transport can be achieved with two‐dimensional polycyclic aromatic hydrocarbons (2D‐ PAHs). Herein, we present an efficient synthesis and characterization of bistetracene derivatives that exhibit a band gap up to 1.71 eV and an increased stability up to 21 times compared to TIPS–PEN and mobility over 0.1 cm2 V−1 s−1 in solution‐processed organic field‐

effect transistors. Based on simple structural consideration, the high stability is attributed to the aromaticity of the bistetracene which is comparable to an anthrancene along each tetracene. According to …
