Patent number: 7825161Abstract: Chemically functionalized fullerenes are useful in various applications as radical scavengers. These chemically functionalized fullerenes offer the advantages of preservation of the high innate radical scavenging efficiency of the fullerene cage and ease of synthesis of fullerene derivatives of desirably altered chemical and physical properties and single isomers. Further, they are based on a common intermediate chemistry and intermediates can be easily functionalized and tailored to various requirements.Type: GrantFiled: December 15, 2004Date of Patent: November 2, 2010Assignee: Nano-C, Inc.Inventors: David F. Kronholm, Jan C. Hummelen, Alexander B. Sieval
