All these ligands present a very rich complexation chemistry with transition metal ions that depends on their specific structure. Thus, they can perform transition metal ion recognition by selecting metal ions [2.65,2.66] according to the coordination features of the ion and the nature, number and disposition of the binding...

It is believed that two crowns bind a K+ ion, thus leading to loosely preassembled bis-pyrene subunits. When the metal ion recognition event occurs in the presence of y-CD, dramatic enhancements of excimer emission are observed, thus providing a method to selectively detect K+ ion in aqueous solution. This ability to sense an ionic analyte is unusual for CD chemosensors. Modification of 28 with other ion binding sites should provide a general method for cation detection.

This chapter is focused on our recent research topics regarding the analysis of complexation reactions at L/L interfaces. We first describe the hydrogen-bond-mediated anion recognition as studied by ion transfer polarography and interfacial tensiometry [22,23], and then alkali metal ion recognition as studied by SHG spectroscopy [24,25].

New potential applications of sorbents in conjunction with a membrane are expected from the development of molecular-imprinted or ionic-imprinted polymers that are capable of metal-ion recognition. This concept based on preparation of matrix in the presence of the molecular or ionic template. After removal of the target molecule/ion the prepared solid can react with the solution of the molecules/ions from which the imprinted molecule/ion should thus be preferentially extracted from the mixture [81-83]. 

Rogers et al. [30] demonstrated that metal ion recognition is possible in ABSs. This was accomplished by investigating the partitioning of group I and 2 cations from alkaline ABSs using 18-crown-6 as an extractant. Crown ethers are known to be very selective complexants for metal ions. A plot...
