In recent years, benzo[1,2-b:4,5-b']difuran (BDF) building block has got increasing attention due to its planar molecular structure, high mobilities, good solubility, rich sources, and no harm to the environment after degradation. Based on these advantages, benzodifuran unit has been widely used in organic photovoltaic materials. A highest power conversion efficiency (PCE) of 9.43% has already been achieved based on BDF unit, revealing its great potentials in organic photovoltaic materials (OPVs). In this paper, the preparation routes of BDF and the latest research progress of photovoltaic materials based on BDF unit are reviewed, and the relationships between based BDF molecular structure and its photovoltaic performances will be mainly addressed.
