Used as a highly stable pigment in specialty coatings and inks due to its exceptional resistance to heat, light, and chemicals. Commonly applied in high-performance industrial paints, particularly where long-term durability is required. Also investigated for use in electrochemical applications such as catalysts in fuel cells and sensors due to its redox-active metal center and extended conjugated system. Its strong absorption in the visible and near-infrared regions makes it suitable for use in photodynamic therapy and organic photovoltaics. Additionally, employed in gas sensing devices because of its electrical response to certain volatile compounds.
