NEW METHOD OF POLYPYRROLE FUNCTIONALIZATION TOWARD MOLECULAR RECOGNITION

A new method of polypyrrole functionalization is described. This metho d involves a direct chemical modification of as-grown polypyrroles con taning leaving groups, such as N-hydroxysuccinimide or N-hydroxyphtala mide. A direct chemical substitution amine groups, such as beta-ferroc ene ethylamine chosen as electrochemical probe, was studied. Furthermo re amino-crown ether was also substituted to polypyrrole and electroch emical recognition properties toward alkaline cations were studied. Th ese results bring an interesting way for easy and effective functional ization polymers toward recognition properties.
