Used as a high-performance organic photoredox catalyst in visible-light-driven chemical transformations. Exhibits strong absorption in the blue region of the visible spectrum, enabling efficient activation under mild conditions. Commonly applied in cross-coupling reactions, C–H functionalization, and polymerization processes where traditional metal-based catalysts may fail. Its rigid molecular structure enhances stability and prolongs excited-state lifetime, improving catalytic efficiency. Also employed in photovoltaic systems and light-emitting devices due to its excellent charge-transfer properties.
