摘要

Nanoscale carbon materials (i.e., fullerenes and nanotubes) are attractive platforms for applications in photovoltaics. These nanoscale materials have extended, delocalized π-electron systems, which, in combination with photoexcited electron donors, may make them useful for managing charge transfer within novel, ultra-high efficient photoelectrochemical cells for water splitting and reduction of CO_2 to fuels. As far as fullerenes and especially C_(60) are concerned, a recent breakthrough in our work includes a 24% efficient charge-separation within a molecular tetrad. The lifetime of the spatially-separated (～49 A) radical pair, which is the product of a sequence of energy and electron transfer reactions, reaches well beyond milliseconds (0.38 s). Such an extended charge separation had not previously been accomplished in an artificial photosynthetic reaction center.
