 Abstract fullerines are compelling molecular materials due to their exceptional robustness against multi-electron reduction. This property has been attributed to several structural factors, such as high symmetry, pyramidalized carbon atoms, and five-membered ring substructures. However, these factors may not be sufficient to explain the origin of this electron affinity. In this study, researchers synthesized a one-dimensional fragment of fullerine, C60, called oligo, by indenylidine. They found that this molecule could accept electrons up to the same amount of five-membered rings present in its main chain. Additionally, UV, this NIR spectroscopy showed that oligo, by indenylidine, had greater absorption in the visible range compared to C60. The authors concluded that the pentagonal substructure of oligo, by indenylidine, is responsible for its increased stability towards multi-electron reduction, which provides a strategy for the design of electron-accepting conjugated hydrocarbons without electron withdrawing groups.
