A fluorescent reagent (1) which has an electron donor and an acceptor at each terminal of linear polyether chain was synthesized, and the complexation behavior of 1 with alkaline earth metal ions was investigated. Quenching of the fluorescence spectrum and changes of 1H-NMR spectrum at the complexation with the metal ions showed the interaction between two moieties in both excited state and ground state.
