Electrochemical sensing of dihydrogen phosphate and adenosine-5'-triphosphate anions by self-assembled monolayers of (ferrocenylmethyl)trialkylammonium cations on gold electrodes.

The effective electrochem. sensing of dihydrogen phosphate and adenosine-5'-triphosphate anions could be achieved in org. electrolytes using self-assembled monolayers of a (ferrocenylmethyl)trialkylammonium cation. The electrochem. response of these modified electrodes is similar to that of the receptor in homogeneous soln. The electrochem. recognition properties of the redox active cationic receptor were fully retained after immobilization on the electrode surface. The recognition abilities of this redox assembly are based on strong ion pairing effects, further reinforced upon oxidn. of the ferrocene centers to ferrocenium. The complexation events could be detected and amperometrically quantified through the emergence of new differential pulse voltammetric peaks corresponding to the electroactivity of the (ferrocenylmethyl)alkylammonium-anion complexes.
