Affinity of Pol(Phenylcyanomethylenefluorene) and Poly(Dicyanomethylenefluorene) Towards Metallic Cations - Uses of the New Interfaces in Electrocatalysis
Anodic oxidation of 2(9H-fluoren-9-ylidene)malononitrile and 2(9H-fluoren-9-ylidene)-2-phenylacetonitrile leads to polyfluorenylidene possessing an affinity towards some metallic cations leading to polymer-metal composites. The efficiency of these new interfaces is presented during the anodic oxidation of hydrazine, formaldehyde, methanol, glucose and sodium azide. For this last substrate, the detection limit with our new polymer-metal composite is lower than 5 X 10(-5) M.
