Abstract

The singlet excited-state lifetime of a terpyridyl platinum(II) pentynyl complex was determined to be $268\pm 87\mathrm{ps}$ by fitting femtosecond transient absorption data, the triplet excited-state lifetime was found to be $62\mathrm{ns}$ by fitting nanosecond transient absorption decay data, and the triplet quantum yield was measured to be 0.16. A ground-state absorption cross section of $2.5\times {10}^{-19}{\mathrm{cm}}^2$ at $532\mathrm{nm}$ was deduced from UV-vis absorption data. Excited-state absorption cross sections of $3.5\times {10}^{-17}{\mathrm{cm}}^2$ (singlet) and $4.5\times {10}^{-17}{\mathrm{cm}}^2$ (triplet) were obtained by using a five-level dynamic model to fit open-aperture Z scans at picosecond and nanosecond pulse widths and a variety of pulse energies.
