Abstract: This patent discloses a composition comprising a substituted fullerene, wherein the substituted fullerene comprises a fullerene core (Cn), wherein n is an even integer greater than or equal to 60, and at least one substituent group bonded to at least one carbon atom of the fullerene core, and at least one adjuvant, wherein the adjuvant is an absorption enhancer or bioavailability enhancer. It also discloses methods of using such compositions to ameliorate oxidative stress diseases or inhibit cell death.
Abstract: Improved methods of fullerene derivative production including use of less solvent, or elimination of solvent, as well as use of shorter reaction times and higher reaction temperatures. Methods useful for production of bis-, tris-, tetra-, penta-, and hexa-fullerene derivatives. Indene is a preferred derivative. The derivatives used in active layers for solar cell applications.

Abstract: The present invention provides a photoelectric conversion material comprising a fullerene derivative represented by the formula C60(R1)5(MLn), wherein: each R1 independently represents an organic group having a substituent; M represents a metal atom; L is a ligand of M; and n is the number of Ls. Further, the present invention also provides a photoelectric conversion device having a self-assembled monomolecular film of the photoelectric conversion material, and a solar cell having the photoelectric conversion device.
Abstract: Disclosed herein are an ion-dissociative functional compound, a method for production thereof, an ionic conductor, and an electrochemical device, the ion-dissociative functional compound being thermally and chemically stable under the condition required of fuel cells and being suitable for use as a material such as protonic conductor in fuel cells. The proton-dissociative functional compound shown in FIG. 1A is composed of a fullerene C60 molecule and about 10 sulfonic acid groups —SO3H as proton-dissociative groups each attached to the fullerene through a difluoromethane group —CF2—. The proton-dissociative functional compound shown in FIG. 1B is composed of fullerene molecules three-dimensionally connected to each other through a linking group —CF2SO2NHSO2CF2—. It contains, as the proton-dissociative group, sulfoneimide groups —SO2NHSO2— and sulfoneamide groups —SO2H2 in addition to sulfonic acid groups.
Abstract: Photovoltaic cells comprising an active layer comprising, as p-type material, conjugated polymers such as polythiophene and regioregular polythiophene, and as n-type material at least one fullerene derivative. The fullerene derivative can be C60, C70, or C84. The fullerene also can be functionalized with indene groups. Improved efficiency can be achieved.

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.
