Zinc Phthalocyanine is widely used in the field of photodynamic therapy (PDT) for cancer treatment. It acts as a photosensitizer, absorbing light to produce reactive oxygen species that can destroy cancer cells. This compound is also employed in organic solar cells due to its excellent light absorption and charge transport properties, enhancing the efficiency of energy conversion. In addition, it is utilized in the development of chemical sensors, where its ability to change color in the presence of specific analytes makes it valuable for detecting gases or pollutants. Furthermore, Zinc Phthalocyanine finds applications in dyeing and printing industries, where its stability and vibrant color properties are advantageous for producing long-lasting and high-quality dyes.
