项目摘要

95-61553 Alford This Small Business Innovation Research Phase I project will attempt to demonstrate that metallofullerenes can be efficiently and economically purified via electrochemical processes. Metallofullerenes are closed carbon cage molecules containing a trapped metal atom or atoms. They are a unique new class of molecules with a variety of potential industrial applications. Because the encapsulated metal atom transfers its electrons to the fullerene shell, metallofullerenes have a substantially different electronic structure than empty fullerenes. An electrochemical purification process based on this large difference has the potential of radically reducing the cost of purifying metallofullerenes as compared to the current purification method which utilizes a very expensive and time consuming two step chromatography process. The prohibitive cost of this chromatography process has prevented pure metallofullerenes from being commercially available_making research on industrial applications of metallofullerenes economically infeasible to date. Development of a relatively inexpensive electrochemical purification process that could be scaled to much larger capactities would help spur the development of industrial applications for metallofullerenes in such fields as superconductors, electronics, nonlinear optics, and pharmaceuticals. During Phase I, the feasibility of electrochemical purification of metallofullerenes will be determined, with further optimization and scale-up of this process planned for Phase II.

这个小企业创新研究的第一阶段项目将试图证明金属富勒烯可以通过电化学过程高效和经济地纯化。金属富勒烯是封闭的碳笼分子，包含一个或多个被捕获的金属原子。它们是一类独特的新型分子，具有多种潜在的工业应用。由于被包裹的金属原子将其电子转移到富勒烯壳层，金属富勒烯与空富勒烯的电子结构有本质上的不同。与目前使用非常昂贵且耗时的两步色谱法的纯化方法相比，基于这种巨大差异的电化学纯化过程有可能从根本上降低纯化金属富勒烯的成本。这种色谱法的高昂成本阻碍了纯金属富勒烯在商业上的应用，使得金属富勒烯的工业应用研究迄今为止在经济上是不可行的。一种相对廉价的电化学净化工艺的发展，可以扩展到更大的容量，这将有助于促进金属富勒烯在超导体、电子、非线性光学和制药等领域的工业应用的发展。在第一阶段，将确定电化学纯化金属富勒烯的可行性，并计划在第二阶段进一步优化和扩大该工艺。
