Synthesis of Phospholes Coordinated to a Heteroatom on the Phosphorous Atom and their Application to Electronic Materials

我们开发了一种以亚磷酸三苯酯为原料合成磷烯的简单方法。用这种方法合成了一系列磷原子上带有芳基的2，3，4，5-四苯基膦。以大约40%的产率获得了它们，并在固态下研究了它们的晶体结构和荧光性质。一些具有芳基的磷烯，如苯基、萘基和五氟苯基，表现出大于30%的内量子效率。一些磷被用作有机场效应晶体管的活性材料，因为它们具有较低的电子迁移率。

We developed a simple method for synthesizing phospholes using triphenyl phosphite. In this method, a series of 2, 3, 4, 5-tetraphenylphospholes having an aryl group on the phosphorous atom was synthesized. They were obtained in approximately 40% yield, and their crystal structures and fluorescence properties were investigated in the solid state. Some phospholes having aryl groups, such as phenyl, naphthyl, and pentafluorophenyl, exhibited an internal quantum efficiency of greater than 30%. Some phospholes have been investigated as active materials of organic field-effect transistors to be low electron mobility.
