Selective unipolarization of an ambipolar polymer semiconductor, PNDTI-BT, by using different self-assembled monolayers, is demonstrated. For p-unipolarization, 1H,1H,2H,2H-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.
通过使用不同的自组装单层，实现了双极聚合物半导体 PNDTI-BT 的选择性单极化。对于 p 型单极化，1H,1H,2H,2H-全氟癸基三乙氧基硅烷最为有效，而对于 n 型单极化，3-(N,N'-二甲氨基)丙基三乙氧基硅烷则是最佳选择。利用这些选择性单极化效应，通过简单的溶液处理工艺制备的基于双极聚合物的互补反相器表现出了极大改善的开关特性和低功耗。
