The alkali metal (Li ϩ , Na ϩ , K ϩ , Rb ϩ , and Cs ϩ ) binding selectivities of caged crown ether compounds are evaluated by way of electrospray ionization mass spectrometry and compared to the binding selectivities of three reference crown ethers, 15-crown-5, 1,7-diaza-15-crown-5, and 18-crown-6.

Electrospray ionization (ESI) was used in conjunction with quadrupole ion trap mass spectrometry to measure metal binding selectivities of bis-crowned clefts in methanol solution. Each of the three cleft compounds contained two 15-crown-5 rings separated by di †erent quinoline spacers. Binding selec
## Abstract Electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI‐FTICRMS) was used to investigate metal ion interactions of the 18 amino acid peptide fragment B18 (LGLLLRHLRHHSNLLANI), derived from the membrane‐associated protein bindin. The peptide sequence B18
