Angelicain is primarily used in the field of photodynamic therapy and organic electronics due to its strong photochemical properties. Its ability to generate reactive oxygen species under light exposure makes it valuable in targeted cancer treatments, where it can selectively destroy tumor cells with minimal damage to surrounding healthy tissue. In organic electronics, Angelicain serves as a component in the development of light-sensitive materials for use in sensors and photovoltaic devices. Additionally, it has been explored as a fluorescent probe in biological imaging, allowing researchers to track cellular processes with high sensitivity. Its stability under UV and visible light enhances its suitability for long-term imaging applications.
