The extent of spin density delocalization in the system is indicated by the Pt and nitrogen spin ranges . The Pt site, characterized by a more extensive and varied spin range, is the primary location for spin polarization and charge transfer interactions. This delocalization enhances the system's ability to absorb light by facilitating electronic transitions between molecular orbitals. Nitrogen, with its narrower spin range, supports this delocalization by stabilizing the charge distribution within the conjugated phenalene framework. The interaction between Pt and nitrogen creates a charge-transfer pathway, which is essential for absorbing visible or UV light, thereby defining the optical absorption spectrum.
