New method of polypyrrole functionalization toward molecular recognition

A new method of polypyrrole functionalization is described. This method involves a direct chemical modification of as-grown polypyrroles contaning leaving groups, such as N-hydroxysuccinimide or N-hydroxyphtalamide. A direct chemical substitution of amine groups, such as β-ferrocene ethylamine chosen as electrochemical probe, was studied. Furthermore amino-crown ether was also substituted to polypyrrole and electrochemical recognition properties toward alkaline cations were studied. These results bring an interesting way for easy and effective functionalization polymers toward recognition properties.
