The US-German joint proposal brings together organic chemistry with molecular electronics. The recently discovered class of so-called diamondoids (nanometer-sized hydrogen-terminated diamonds) is the ideal subject because it is challenging as well as highly promising and because it joins two otherwise unrelated scientific groups and disciplines. The effects in the reduction in size in going from macroscopic diamond to nanodiamonds will be thoroughly examined by a) making functional derivatives (alcohols, thiols, acids, amines, dienes, and others) that allows the attachment of the nanodiamonds to surfaces (Au, Al, Si etc.) and b) measuring their electronic properties. One particularly important feature is the proposed negative electron affinity of diamondoids that would make them ideal electron emitters for a large number of applications. These two aspects also describe the work distribution between the groups at the Justus-Liebig University Giessen and the Gabelle Lab for Advanced Materials at Stanford University. No group alone could tackle what we propose because significant expertise is required to provide appropriately functionalized hydrocarbons on one side and high-quality molecular electronics measurements on the other. The mutual work is complemented by computational chemistry studies supporting the experimental measurements. Keywords: alkane functionalization, diamondoids, molecular electronics, negative electron affinity materials.

美德联合提案将有机化学与分子电子学结合在一起。最近发现的所谓的类金刚石（纳米尺寸的氢终止金刚石）是理想的主题，因为它具有挑战性，并且非常有前途，因为它加入了两个原本无关的科学团体和学科。a）制备允许纳米金刚石附着到表面（Au、Al、Si等）的功能衍生物（醇、硫醇、酸、胺、二烯等），以及B）测量它们的电子性质。一个特别重要的特征是金刚石的负电子亲和力，这将使它们成为大量应用的理想电子发射体。这两个方面也描述了在吉森的Justus-Liebig大学和斯坦福大学的Gabelle先进材料实验室的小组之间的工作分配。没有一个小组能够单独解决我们的建议，因为需要大量的专业知识来提供适当的官能化碳氢化合物和高质量的分子电子学测量。相互的工作是由支持实验测量的计算化学研究补充。关键词：烷烃官能化、类金刚烷、分子电子学、负电子亲和势材料。
