利用专门快速和连续的旋转印刷方法，即凹版印刷和柔性版印刷，已经制备了互补环形振荡器，使得所有层都被相加沉积，并且不涉及任何额外的图案化或互连步骤。这要归功于一种可印刷的空气稳定的n型有机半导体的问世，也就是一种小分子聚苯衍生物的问世。对于两种类型的晶体管使用相同的介质，n型晶体管的特性与基于先前使用的有机半导体6，13-双(三异丙基硅乙炔)并五苯的p型晶体管的特性相当相似。印刷电路对单个晶体管参数的变化具有很强的抵抗力，并且在所有相关特性方面都显著优于可比的单极电路。这种优异的性能可以归因于互补电路，从而为印刷电路的情况展示了其优势。
A complementary ring oscillator has been prepared using exclusively fast and continuous rotary printing methods, namely, gravure and flexographic printing, so that all layers were additively deposited and no additional patterning nor interconnecting step whatsoever was involved. This became possible due to the availability of a printable air-stable n-type organic semiconductor, i.e., a small molecule perylene derivative. Using the same dielectric for both types of transistors, the characteristics of the n-type transistors are reasonably similar to the ones of the p-type transistors, which are based on the previously used organic semiconductor 6,13-bis(triisopropylsilylethynyl) pentacene. The printed circuits are robust against variations of individual transistor parameters and significantly outperform comparable unipolar circuits in terms of all relevant properties. The superior performance can be attributed to complementary circuitry, the advantage of which is thereby demonstrated for the case of printed circuits.
