Outline of Final Research Achievements

We have arranged various metallo-porphyrins and metallo-phthalocyanines inside the stacked assemblies connected through fourfold rotaxanes. We also investigated the intermolecular electronic communication between the components inside the fourfold rotaxane stacked assemblies by electrochemical measurements. On the other hand, we found that a fourfold rotaxane heterodimer and a tetraanionic porphyrin formed a 1:1-type stacked assembly through quadruple electrostatic interaction. Moreover, it was found that the electronic state of the fourfold rotaxane heterodimer was changed significantly upon complexation with tetraanionic porphyin. This indicates that this ionic complexation is useful to control the activity of supramolecular catalysts or the conductance of single molecular wire based on the fourfold rotaxane assembly.
