Cobaltporphyrins having dendrimer side-chains were synthesized, and the oxygen-sensing properties of the modified electrode systems evaluated by electrochemical measurement. Such cobaltporphyrins catalyzed the twoelectron reduction of oxygen on electrodes. As oxygen sensors in modified electrode systems, (<b>i</b>) the current of oxygen reduction increased linearly with the concentration of dissolved oxygen, (<b>ii</b>) the response was reversible and rapid, and (<b>iii</b>) the modified electrode systems were more stable than the cobaltporphyrin monomermodified electrode under hydrodynamic conditions. These results support the potential of modified electrode systems as oxygen sensors.
