Abstract
The development of organic complementary circuits has been largely limited by the development of suitable organic n-channel transistors. However, recent advances have led to materials such as the high-mobility air-stable n-channel organic semiconductor, N, N′-bis(n-octyl)-dicyanoperylene-3,4:9, 10-bis(dicarboximide), PDI-8CN2. Here, the fabrication of an organic complementary D flip-flop using PDI-8CN2 n-channel transistors and pentacene p-channel transistors is described. The measured clock-to-output delay is 25 μs for 1 kHz, and 14 μs at the clock frequency of 5 kHz. This is the fastest clock speed for an organic complementary circuit yet achieved.
