Selective unipolarization of an ambipolar polymer semiconductor , PNDTI‐BT, by using different self‐assembled monolayers, is demonstrated. For p‐unipolarization, 1 H ,1 H ,2 H ,2 H ‐perfluorodecyltriethoxysilane is most effective, whereas for n‐unipolarization, 3‐( N , N ′‐dimethylamino)propyltriethoxysilane is the best. Using these selective unipolarization effects, the complementary inverters based on the ambipolar polymer fabricated by a simple solution process show greatly improved switching behaviors with low power consumption.
