摘要

Four cyclometalated Pt(iv) compounds, 1a,b and 2a,b, were successfully obtained by oxidative addition of I_2 to 2-phenylpyridinate (PhPy) and Nile Red (NR) derived Pt(ii) complexes with acetylacetonate (acac) or hexafluoroacetylacetonate (hacac) ancillary ligands. Single crystal X-ray diffraction, electrochemical, photophysical and computational studies have been performed in comparison with the analogues Pt(ii) compounds, shedding new light on the role of the oxidation state of the metal centre towards both the luminescence properties and the dioxygen quenching.
