The absorption spectrum (Figure ) of the N-Pt-N phenalene derivative (Figure ) reveals three distinct oscillation domes in the ranges of 420-515 nm, 515-575 nm, and 575-625 nm, respectively. These domains correspond to specific electronic transitions and their corresponding energy levels. The presence of these clusters indicates that the material exhibits multiple absorption bands in the visible region, signifying a broad absorption profile. These peaks correspond to transitions between molecular orbitals from HOMO to LUMO or higher excited states, indicative of significant electronic states in the material. The high intensity observed in the range of 420-515 nm420-515 nm suggests strong light absorption in the blue to green region of the spectrum, while the peaks at longer wavelengths (515-625 nm515-625 nm) demonstrate the model's ability to absorb light in the yellow to red region. This extensive absorption range renders the material well-suited for leveraging a more substantial portion of the solar spectrum, thereby augmenting its light-harvesting capabilities.
