Abstract
Two types of N‐substituted pyrroles with azide and terminal alkyne groups have been synthesized and electropolymerized. “Click” chemistry, specifically Huisgen 1,3‐dipolar cycloaddition, was used as a general method for functionalization of the polypyrrole films. Several model compounds, including redox active (quinone), bioactive (cholic acid) and recognition elements (carbohydrate and thymidine) could easily be attached onto the electrode surfaces without loss of functionality or the electroactivity of the underlying conducting polymers. The results suggest that the polypyrrole films are clickable and provide a novel biocompatible and versatile platform for efficient modifications on electrode surfaces.
