The spin variations also suggest dynamic charge redistribution when the system interacts with light . The elevated spin density on platinum (Pt) signifies its role as the primary site for electron excitation and subsequent charge separation, while nitrogen functions as a secondary site that stabilizes the excited state. This charge redistribution process is pivotal in the formation of long-lived excitons, which are critical for photocatalysis. Efficient separation of photogenerated electron-hole pairs minimizes recombination, enhancing the system's ability to harness light energy for catalytic reactions.
