  • Organic material photodiode
    Publication number: 20060159611
    Abstract: The present invention relates to a photodiode including a photo-active layer, which layer includes at least one electron donating material, and at least one fullerene derivative as an electron accepting material. The present invention further relates to a method for making such a photodiode, to a photo-active layer and to a fullerene derivative.

  • High-efficiency fullerene-based radical scavengers
    Publication number: 20050245606
    Abstract: 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.
