Abstract

The reaction between a suitable cyanine and a bicyclophosphane gives in good yield new eight membered cyclic phosphonate podands. Their complexation with calcium and magnesium cations induces an enhancement of the fluorescence intensity. Thus, these labelled heterocycles are convenient sensors for the detection of divalent cations. © 2003 Elsevier Science Ltd. All rights reserved.
