Abstract

The photophysical behavior of the ruthenium (I1) porphyrins depends dramatically on the axial ligands coordinated to the central metal ion. We have measured the picosecond and slower time scale transient absorption spectra and kinetics, emission data, and ground-state absorption spectra for two classes of complexes: RuP (CO)(L) and RuP (L),. Results are compared for complexes in which the porphyrin macrocycle (P) is tetraphenylporphyrin ( ...
