Abstract/Artist's Statement

Platinum compounds, especially d8 Pt (II) compounds have desirable photochemical properties including long-lived excited states and high quantum yields, which are useful to the production of organic light-emitting diodes (OLEDs) and light-emitting electrochemical cells (LECs). Understudied in this field are d6 Pt(IV) compounds, which have the potential to exhibit the same useful properties and being six-coordinate, may allow for fine-tuning with additional ligands. In this study, Pt(IV) complexes were modified by ligand substitution, as well as synthesized by reaction of appropriately designed pincer ligands with the tetramethyl platinum precursor, Pt2Me4(μ-SMe2)2, in order to investigate their emission spectra as a function of oxidation state and ligand architecture. The Pt(IV) compounds were characterized by NMR and emission spectroscopy. Optimized molecular geometries and reaction pathways were calculated ab initio using Density Functional Theory.
