Gas Phase Cluster Synthesis

化学系授予加州大学伯克利分校的这项初学者奖学金支持杰弗里·R·朗教授的研究。本研究的主题是团簇的气相合成。目标是大量合成配体稳定的二元金属-阴离子簇合物类似物。在专门设计的气相团簇反应器中，通过对合适的二元固体进行阻性加热，大规模地产生团簇。然后，团簇在气相中与所选择的挥发性配体反应，稳定的产物在反应堆的液氮冷却壁上凝固。这种技术的成功演示可能使人们能够进入仅受金属和非金属元素二元组合数量限制的团簇化学领域。这项研究为气相团簇的整体合成提供了一种通用的方法，从而使人们能够进入尚未探索的团簇化学领域。该方法可能产生与长期寻找的具有生物重要性的簇相关的产品。

This starter grant award of the Chemistry Division to the University of California at Berkeley supports the research of Professor Jeffrey R. Long. The theme of the research is gas phase synthesis of clusters. The goal is bulk synthesis of ligand-stabilized analogues of binary metal-anion clusters. In a specially designed gas phase cluster reactor, clusters are generated on a large scale via resistive heating of an appropriate binary solid. The clusters then react in the gas phase with a volatile ligand of choice, and the stabilized product solidifies on the liquid nitrogen cooled walls of the reactor. Successful demonstration of such a technique potentially enables access to a domain of cluster chemistry limited only by the number of binary combinations of metallic and nonmetallic elements. This research provides a general method for bulk synthesis of gas phase clusters and thus enables access to unexplored realms of cluster chemistry. The method may yield products of relevance to long-sought clusters of biological importance.
