Used as a pigment in coatings, plastics, and printing inks due to its intense blue-green color and excellent lightfastness. Common in automotive paints and industrial coatings where durability and color stability are critical. Also applied in electronic materials, such as organic semiconductors and photovoltaic devices, thanks to its ability to conduct charge and absorb light in the visible and near-infrared range. Employed in sensors and electrochromic devices because of its redox activity and stable electrochemical behavior. Its thermal stability makes it suitable for high-temperature applications in functional films and optoelectronic components.
