The singlet excited-state lifetime of a terpyridyl platinum(II) pentynyl complex was determined to be by fitting femtosecond transient absorption data, the triplet excited-state lifetime was found to be 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 at was deduced from UV-vis absorption data. Excited-state absorption cross sections of (singlet) and (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.
