✦ Synopsis

Abstract

Two bipyridine derivatives were synthesized and characterized, and their ability to act as sensors for carboxylates was evaluated by UV/Vis and fluorescence studies. The influence of the substituents of the thiourea groups on the stoichiometry of the resulting dicarboxylate complexes was established. Conformational changes in the bipyridine moiety under different conditions were evaluated.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
