| Research Abstract |
The spherical shape of buckminsterfullerenes (C_<60>) makes these carbon allotropes ideal probes for the investigation of electron transfer reactions, especially in light of aspects regarding the electron transfer theory by Marcus. Using photoexcited fullerenes (i.e., the singlet or triplet excited state) widens the scope of electron transfer reactions. This assumption stems from the fact that excitation of fullerenes enhances both the electron acceptor and the donor ability of the photoexcited fullerenes.
This study has focused on both the fundamental electron transfer properties of ground state and excited state fullerenes and the chemical processes associated with the thermal and photoinduced electron transfer reactions of fullerenes to develop a number of new redox processed involving fullerenes. The rich redox properties of fullerenes and their derivatives, in both the ground and excited states, have also rendered them important three-dimensional components for the design of novel artificial photosynthesis systems.
