Abstract
Abstract In acetonitrile solutions, the deprotonated form of 1-pyrenebutyric acid ( 1 ) forms 1:2 (metal:ligand) complexes with Zn 2+ , Cu 2+ , Fe 2+ , Fe 3+ , and earth alkali metal ions. The complexation process leads two pyrene moieties in close contact, so that dimers are formed, causing strong changes in the absorption and fluorescence spectra. Taking advantage of these changes, very low concentrations of earth alkali metal ions can be detected, suggesting 1 as a good prototype of a new family of fluorescent sensors.
