New chiral dicarbazole derivatives functionalized by N ‐hydroxysuccinimide and pentafluorophenoxy groups have been synthesized and electrochemically characterized. Upon oxidative electropolymerization of these monomers in organic electrolytes electroactive poly(dicarbazole) films were formed on platinum electrodes. The subsequent chemical grafting of glucose oxidase on the poly(dicarbazole) films was easily performed by immersion in an enzymatic aqueous solution. The amperometric response of the resulting biosensors to glucose has been studied at 0.6 V vs. aqueous saturated calomel electrode.
