Ultraviolet photodepletion spectra of dibenzo-18-crown-6-ether complexes with alkali metal cations (M+-DB18C6, M = Cs, Rb, K, Na, and Li) were obtained in the gas phase using electrospray ionization quadrupole ion-trap reflectron time-of-flight mass spectrometry. The spectra exhibited a few distinct absorption bands in the wavenumber region of 35 450−37 800 cm−1. The lowest-energy band was The construction of self-organized adlayers of dibenzo-18-crown-6 and its inclusion complex with potassium ion on a Au(111) surface was independently achieved by potential-controlled adsorption.

Mg 2+ showed predominantly strong binding affinity in the gas phase because of strong polarization of CO bonds by cation. In aqueous solution, binding free energy differences became smaller among these dications.
