摘要：

Complexes of the type [crown + M]+ were observed following laser desorption ionization of 18-crown-6 molecules 'doped' with K+, Cs+, and Ba+. Laser desorption ionization of 15-crown-5 and 12-crown-4 'doped' with the same metals gave [(crown)2 + M]+ type sandwich complexes. Binding energies of crown ethers with different metal ions in all such complexes have been estimated from appearance energies obtained in the collisionally-activated dissociation of the corresponding laser desorbed complexes.
