Synthesis and electrochemical characterization of original "TEMPO" functionalized multiwall carbon nanotube materials: Application to iron (II) detection.

We report the synthesis and electrochem. behavior of an original catalyst bearing a 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) unit and a pyrene group. Anchoring of this bi-functional mol. by $π$ -stacking onto multiwalled carbon nanotubes allows the study of the electrochem. properties of the compd. in the immobilized state. These resulting functionalized TEMPO materials were used to detect iron(II) in soln. with an exptl. detection limit of 3.9 × 10- 8 mol L- 1 and a linear range between 7.8 × 10- 8 and 1.4 × 10- 6 mol L- 1.
