Outline of Final Research Achievements

In this project, we have synthesized and characterized a series of redox-active macrocyclic coordination clusters in which oxo-centered trimetallic frameworks are linked by bidentate ligands, and their potential utility as molecular quantum cellular automata (MQCA) cell has been examined. The molecular structure of the macrocyclic tetramer complex has been identified by single-crystal X-ray diffraction analysis. Cyclic voltammetry has revealed that the compound shows two-step two-electron oxidative process. The stability of the dicationic mixed-valent state is tuned by the electron-donating/withdrawing ability of the ancillary pyridyl ligands. The redox wave splitting larger than 200 mV is suited for use of this coordination cluster as the MQCA cell.
