gave a series of novel T-shaped organic π-conjugates. The electronic properties of the conjugates were studied experimentally by the combination of cyclic voltammetry and UV-vis spectroscopy. Their HOMO and LUMO energy levels are estimated to be about −5 eV and −3.2 eV, which are the air operating stability ranges in the p-channel and n-channel field effect transistors, respectively. Only one conjugate
描述了一种容易的合成方法,用于π-膨胀的四硫富瓦烯衍生物。3,6-二氯哒嗪稠合的四硫富富烯的Suzuki反应与苯基硼酸 或者 联苯硼酸给出了一系列新颖的T形有机π共轭物。通过循环伏安法和紫外可见光谱法的结合,对缀合物的电子性质进行了实验研究。它们的HOMO和LUMO能级估计约为-5 eV和-3.2 eV,分别是p沟道和n沟道场效应晶体管中的空气工作稳定性范围。经验证,只有一个带有较长烷基链的共轭物(n = 1,R = n -C 18 H 37)能在介晶相中自组装成层状结构,其薄膜器件的最佳载流子迁移率是4.5 ×10 -5 cm 2 V -1 s -1。
