Benzo[b]phosphole oxides exhibit attractive optical and electronic properties for applications as materials for organic light-emitting devices, photovoltaics and field-effect transistors. Recently, benzo[b]phosphole oxides introduced an electron-donating substituent have been emerged. These molecules show strong fluorescence and solvatochromism depending on the electron-donating substituent. This review highlights recent progress in developing donor-acceptor-type benzo[b]phosphole oxides and their photophysical properties.
