Widely used in photodynamic therapy, this compound acts as a photosensitizer that generates reactive oxygen species when exposed to light. It targets cancer cells selectively, minimizing damage to healthy tissue during treatment. Its strong absorption in the visible light range makes it effective for activating therapeutic responses in tumors located near the surface. It is also applied in catalysis, especially in oxidation reactions, where it facilitates selective transformations under mild conditions. Due to its stable coordination structure, it serves as a catalyst in environmental and industrial processes, such as pollutant degradation and organic synthesis. In addition, this compound is employed in sensor technologies, particularly in detecting gases and biological molecules, thanks to its distinct optical and electronic responses upon binding analytes. Its use extends to research in artificial photosynthesis and molecular electronics, where electron transfer properties are crucial.
