Extended isoindigo core: synthesis and applications as solution-processable n-OFET materials in ambient conditions

摘要

Two isoindigo derivatives fused with benzothiophene (C20-DBTII) and benzofuran (C20-DBFII) heterocycles have been synthesized. Solution-processed OFETs based on C20-DBTII showed ambient-stable ambipolar charge transport behaviour. OFETs based on the C20-DBFII show n-channel behaviour with electron mobility up to 0.074 cm(2) V- 1 s(-1) in ambient conditions.
