Potassium cation induced switch in anion selectivity exhibited by heteroditopic ruthenium(II) and rhenium(I) bipyridyl bis(benzo-15-crown-5) ion pair receptors
Cl- and H2PO4- anion selectivity properties of new heteroditopic RuII and ReI bipyridyl bis(benzo-15-crown-5) receptors are remarkably dependent upon the presence of co-bound intramolecular sandwich crown ether complexed K+.

Cooperative binding of potassium cation and chloride anion by novel rhenium(I) bipyridyl amide crown ether receptors
New rhenium(I) bipyridyl amide crown ether receptors are prepared and shown to complex K+Cl- ion pairs in which crown ether complexation of the potassium cation cooperates in the binding of chloride anion.
