Abstract: The present invention generally provides compositions including carbon-containing molecules, and related methods. In some cases, the present invention relates to aromatic molecules comprising functional groups bonded to the aromatic portion of the molecule, including nonplanar portions of the molecules. Methods of the invention may provide the ability to introduce a wide range of functional groups to carbon-containing molecules. In some cases, methods of the invention may be performed using relatively mild reaction conditions, such as relatively low temperature, low pressure, and/or in the absence of strong acids or strong bases. The present invention may provide a facile and modular approach to synthesizing molecules that may be useful in various applications including photovoltaic devices, sensors, and electrodes (e.g., for electrocatalysis).

Abstract: Disclosed and claimed herein are e,e,e malonic acid/acetic acid tri-adduct of buckminsterfullerene of the general formula C60R3, wherein each R is independently selected from groups of the formula —CR1R2 wherein each R1 and R2 is independently selected from the group consisting of —H and —COOH, provided, however, that at least one of the R1's and R2's is a hydrogen. Processes for preparing and uses of the same for treating neuronal injury and for life-extension are also disclosed and claimed herein.
