| Luminescent platinum(II) diimine complexes are of particular interest because of their potential applications in areas such as chemical sensing and multielectron photocatalysis. In an effort to better understand the rich photophysical and photochemical properties of this class of compounds, we are investigating a platinum(II) diimine complex, Pt(phen)(bpa)2 (phen=1,10-phenanthroline; bpa- =1-butyl-4-phenylacetylide). This compound has been characterized by 1H-NMR spectroscopy, elemental analysis and UV-visible absorption spectroscopy. The complex exhibits long-lived luminescence in fluid solution. In dilute solutions, the emission maximum occurs at 612 nm. With increasing concentration a new feature grows in near 740 nm. The low energy band is tentatively attributed to excimer emission. Steady-state and time-resolved emission experiments to determine the lifetime, quantum yield and self-quenching rate will be discussed. |
