✦ Synopsis

An easy and fast method using electrospray ionization mass spectrometry for determination of the stability constants (logK s ) of different metal-ion complexes with crown and lariat crown ethers has been developed. This method has been verified with known logK s by using either excess crown ether or excess metal ion. Stability constants of Li + , Na + and K + with seven lariat crown ethers, including four new compounds, have been determined.
