摘要：

Direct evidence of photoejection of lithium and calcium ions from a crown-ether-linked merocyanine is provided by picosecond pump-probe supercontinuum spectroscopy. The photoejection process takes place in less than 5 and 20 ps for the Li+ and Ca2+ complexes, respectively. The stability constants of the complexes in the excited state are estimated to be two orders of magnitude lower than in the ground state.
