The spectral and dynamic features of photoexcited radical ions have been studied by ultrafast spectroscopy. The excited state absorption spectrum, lifetimes and the influence of parameters like excess excitation energy, solvent or temperature on the photophysical behavior has been investigated for a series of chemically distinct systems chosen such as to span a range of chemical diversity, excited state energies (1 to 2 eV) and oxidation state (cationic or anionic). The radical ions have been generated either chemically or electrochemically in a home-built flow cell. The results reveal that the lifetime of the lowest electronic excited state, D1, is on the order of picoseconds only. Wurster's salts, for example, have a D1 lifetime of 0.2 ps...
