We report 7- and 15-stage spin-cast contact-crystallized 2, 8-difluoro-5, 11-bis(triethylsilylethynyl) anthradithiophene (diF-TESADT) organic thin-film transistor (OTFT) ring oscillators on plastic substrates with a maximum frequency of more than 22 kHz and a propagation delay of less than 3.3 μs/stage at a supply bias of -80 V. The circuits have stable operation for a supply bias as small as -3 V (25-30 μs/stage). Spin-cast diF-TESADT OTFTs from a toluene solution on plastic substrates have a mobility of 0.1-0.2 cm2/V · s with a contact-related microstructure from pentafluorobenzenethiol-treated Au source and drain electrodes.
