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.

研究了一种以亚磷酸三苯酯为原料合成磷酸孔的简便方法。在此方法中，合成了一系列在磷原子上有芳基的2,3,4,5 -四苯基磷孔。它们的产率约为40%，并在固体状态下研究了它们的晶体结构和荧光性质。一些含有芳基基团的磷光孔，如苯基、萘基和五氟苯基，其内部量子效率大于30%。一些具有低电子迁移率的磷孔被研究作为有机场效应晶体管的活性材料。
