Matériaux moléculaires pour l'analyse voltammétriques de cations métalliques : récepteurs à multiples centres rédox et polymères complexants.

Abstract : This work deals with the conception of molecular materials for in situ detection and determination of cationic species using two electrochemical analysis approaches : electrochemical recognition and stripping voltammetry.
The first part concerns the study of two binding receptors containing multiple redox active centers. Each redox active molecular structure turned out to display original and specific electrochemical recognition in aqueous or organic media and they were used for electrochemical detection, quantification and differentiation of metallic and lanthanide cations. This recognition is based either on intramolecular electronic communication between the redox centers or on the coordination mode of the formed complexe.
In the second part, complexing electrode materials which allow electrochemical detection and determination of metallic cations were elaborated and optimised to develop new sensitive and selective electroanalytic devices for trace metal cations analysis.
