title: A densely decorated disubstituted ferrocene as an ion-pair recognition receptor.
abstract: A functionalized 1,1'-disubstituted ferrocene acts as an electro-optical ion-pair receptor for Mg(2+), Ca(2+), Cd(2+), and Zn(2+) cations in the presence of a co-bound H2PO4(-) anion, through perturbation of the redox potential of the ferrocene unit, enhancement of the fluorescence and a noticeable colour change.
