| Research Abstract |
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.
