Abstract Time-resolved transient absorption and gain spectra of DCM-crown and its complexes with Li+ and Ca2+ in acetonitrile are measured in the wavelength range 370–670 nm after subpicosecond excitation at 425 nm. The results give evidence for the fast formation of free DCM-crown from both excited complexes, with a faster rate for the Li+ complex. A two-step mechanism is found for the initial decay (within 30 ps) of the free DCM-crown.
