| Outline of Final Research Achievements |
We have synthesized novel nonaromatic π-conjugated macrocycle based on various tetrathiafulvalene-derived structures. The formation of supramolecular ensembles composing of two dicationic porphyrin-bridged extended TTF derivative and a tetraanionic porphyrin derivatives were characterized and achieved the extremely long-lived photoinduced charge separated states (τCS ~ 83 ms). In a case of TTF-annulated expanded porphyrin, the protonation-induced thermal charge separation between the porphyrin and TTF units was observed.
In a similar design principle, we have also succeeded in the preparation of stable π radical complex based on a contracted N-confused hexaphyrin derivatives.
