Used as a catalyst in oxidation reactions, particularly in biomimetic catalysis that mimics cytochrome P450 enzymes. It facilitates selective oxidation of hydrocarbons under mild conditions, making it valuable in fine chemical and pharmaceutical synthesis. Also investigated in photocatalytic systems for organic transformations and environmental remediation due to its light absorption properties. Its structure supports electron transfer processes, useful in developing sensors and electrocatalytic devices. Additionally, explored in photodynamic therapy research for targeted oxidative damage in cancer cells.
