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.

巴克敏斯特富勒烯 (C_<60>) 的球形形状使这些碳同素异形体成为研究电子转移反应的理想探针，特别是考虑到 Marcus 的电子转移理论。使用光激发富勒烯（即单线态或三线态激发态）拓宽了电子转移反应的范围。这一假设源于富勒烯的激发增强了光激发富勒烯的电子受体和供体能力。本研究重点关注基态和激发态富勒烯的基本电子转移特性以及与富勒烯的热和光致电子转移反应相关的化学过程，开发了许多涉及富勒烯的新型氧化还原工艺。富勒烯及其衍生物在基态和激发态下丰富的氧化还原特性也使其成为新型人工光合作用系统设计的重要三维组件。
