Abstract

Geometric immobilization of polyamine ligands is expected to change their binding properties toward practical ion discrimination. Chemosensor 5 senses only two transition metal ions in water- Hg(II) (K(d) ≤ 1 μM) and Cu(II) (K(d) 56 μM)- which can be compared with bindings of a non-immobilized reference compound (9-(trpnmethyl)-anthracene; 3) with Hg(II) (K(d) 14 μM) and Cu(II) (K(d) 39 μM). A related bridged cyclen derivative (7) showed no effect on fluorescence by any metal ion examined.
