By introducing the naphthyl group into the 2,6-positions of anthracene, two different anthracene derivatives, 2,6-di(2-naphthyl)anthracene (2,6-di(2-Na)Ant) and 2,6-di(1-naphthyl)anthracene (2,6-di(1-Na)Ant) were synthesized. The tiny change in the substitution site of the naphthyl group leads to a significant difference in the molecular packing and further exerts a great impact on their optoelectronic
通过将萘基引入蒽的2,6-位,可以得到两种不同的蒽衍生物:2,6-二(2-萘基)蒽(2,6-di(2-Na)Ant)和2,6-di合成了(1-萘基)蒽(2,6-二(1-Na)Ant)。萘基取代位的微小变化导致分子堆积的显着差异,并进一步影响了它们的光电性能。用于2,6-di(2-Na)Ant的薄膜场效应晶体管的电荷迁移率高达2.1 cm 2 V -1 s -1,而2,6-di(1-Na)Ant的电荷迁移率没有。此外,2,6-di(2-Na)Ant薄膜光电晶体管显示出6.9×10 3 AW -1的光敏度,具有2.6×10的高光敏性6和3.4×10 16 Jones的出色探测性能,这是迄今为止报道的薄膜有机光电晶体管的最高性能之一。
