| Outline of Final Research Achievements |
The dynamic redox (dyrex) systems undergo reversible bond formation/cleavage upon electron transfer. This characteristic feature provides those redox systems with electrochemical bistability, by which oxidation of the donor and reduction of the cationic species occur at difference potentials. Such separation prevents the exchange of electrons between the neutral state and the cationic state, whereas the activation energy for the corresponding process in ordinary redox pairs is negligible. Thus, bistability in dynamic redox pairs can lead to their use in unimolecular memory because one molecule can be considered to be one digit if the two redox states are assigned values of 0 and 1 (e.g., the neutral donor is 0 and the cationic state is 1). We have developed several promising dyrex systems in this work, which would be used as prototypes for developing advanced molecular memory unit.
