Molecular recognition of Co(III)-containing complex monocations by calix[4]resorcinarenes in alkaline water-methanole media
Abstract
It is shown by pH-metric titration that calix[4]resorcinarenes can bind cobalt(III)-containing complex monocations in alkaline water-organic media; the binding constants depend on the complex cation structure and are independent of the charge of the calix[4]resorcinarene anion.
