Used in organic electronics as a semiconductor material due to its extended π-conjugation and stable keto-form structure. It serves as an active component in organic field-effect transistors (OFETs) and dye-sensitized solar cells (DSSCs), where it enhances charge carrier mobility and light absorption in the visible range. Its rigid, planar framework improves molecular packing in thin films, contributing to better device performance. Also investigated as a sensitizer in photodynamic therapy due to its ability to generate reactive oxygen species under light irradiation.
