Abstract

Fluorescent sensor for 3d divalent metal ions have been designed by means of a supramolecular approach: a 2,2'- bipyridine group (the signalling and simultaneously receptor subunit) linked to either a cyclic aza-3n-crown-n group (the anchor). Occurrence of the metal-receptor interaction is signalled through the quenching of bipyridine fluorescence. When the receptor is able to promote a photoinduced energy- transfermechanism, quenching take place. Metal ions can be distinguished (e.g. Cu^II from other transition metal ions).
