Organic complementary inverters based on inverted coplanar organic TFTs employing two vacuum-deposited small-molecule semiconductors were fabricated on flexible substrates. The source and drain contacts of the TFTs were functionalized with pentafluorobenzenethiol (PFBT) or 4-(methylsulfanyl)-thiophenol (MeSTP). For the optimum combination of materials, the inverters have characteristic signal-delay time constants below 2 µs at a supply voltage of 2 V.
