Popis: Recent research into organic semiconductors for organic thin-film transistors (OTFTs) – as alternatives to amorphous silicon-based systems – has yielded improved synthetic and fabrication techniques for devices with great potential for the use in consumable electronic applications.[1–3] To realize the advantages of organic semiconductors in practical applications, OTFTs fabricated through solution processing (spin-coating, casting, or printing) on flexible substrates are strongly desired. Although many groups have developed OTFTs incorporating soluble small-molecule or polymer semiconductors, the number of available hole-transporting materials overwhelms the number of electron-transporting materials.[4–6] Preparing efficient organic integrated circuits at low cost requires soluble hole- and electron-transporting materials that ideally exhibit comparable electrical performance. At present, the development of highperformance n-channel OTFTs remains a challenge, especially when using attractive fabrication processes (e.g., solution processing).
