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.

Disclosed are compositions of mixed fullerene derivatives with utility in organic semiconductors, and methods of making and using such compositions. In certain embodiments, the present invention relates to compositions of mixed fullerene derivatives further comprising one or more additional fullerene-based components within specified ranges. In certain other embodiments, the invention relates to methods of producing mixed fullerene derivatives of a specific composition from mixed fullerene starting materials, or pure fullerene derivatives of a specific composition from mixed fullerene derivatives. In yet other embodiments, the invention relates to semiconductors and devices comprising a composition of the invention.
Abstract:
A method of processing fullerenes includes generating a gas stream having suspended soot particles and condensable gases, wherein the condensable gases comprising fullerenes, and separating at least a portion of the condensable gases from the suspended soot particles using a gas/solid separations process. At least a portion of the fullerenes in the condensable gases can be condensed and collected after separation of the condensable gases.

Abstract:
A mode of combustion and multi-component reactor to accomplish this mode of combustion are disclosed which produces fullerenes and fullerenic material by combustion. This mode consists of de-coupling an oxidation region of a flame from a post-flame region, thus giving greater control over operating parameters, such as equivalence ratio, temperature, and pressure; allows conditions of the operating parameters of the combustion reaction to be attained which would not be easily attained by conventional methods; and offers the ability to more easily stabilize the combustion reactions to allow for higher throughputs of fuel and oxidant. Several embodiments of a primary zone of a multi-component reactor are also disclosed. Said primary zone serves as the oxidation region, operates on the principle of providing recycle to the reacting combustion mixture, and which may be operated as approximately a well-mixed reactor. A secondary zone is also disclosed which provides further residence time for reaction and the ability to control operating parameters, operates on the principle of minimizing recycle of the reacting combustion mixture. The secondary zone may be operated as approximately a plug-flow reactor. The primary and secondary zones may be operated in conjunction or either one alone.
