The Analytical & Surface Chemistry Program of the Division of Chemistry, in the Directorate of Mathematical & Physical Sciences of the National Science Foundation, will support research by Theodore L. Einstein of the University of Maryland, College Park and Ludwig Bartels of the University of California, Riverside. The goal of this work is to understand how particular organic molecules assemble into large regular honeycomb patterns with open pores having diameters of 5 nm. To explore how general this behavior is, Bartels will perform experiments on different molecules and substrate materials in conjunction with theoretical calculations by Einstein that seek to explain the short-range structure in terms of hydrogen bonds and the large pores in terms of the electronic structure of the substrate. With a command of the interaction mechanisms, Bartels and Einstein will seek to engineer the size of open pores and perhaps also the pattern of the molecular networks. Such surfaces can serve as templates for growing patterned films on surfaces for applications ranging from storage technology to heterogeneous catalysis. Educational benefits include the training of graduate students and postdoctoral associates in state-of-the-art techniques for imaging at the atomic scale and for simulating systems in which comparatively small energies and subtle effects determine the overall geometry. It is also an outstanding opportunity for synergistic and close collaboration between physics-based theory and chemistry-based experiment, offering the involved students highly interdisciplinary training.

国家科学基金会数学与物理科学局的化学分析局分析与表面化学计划将支持马里兰大学公园，大学公园和加利福尼亚大学里弗斯大学拉德维希·巴特尔斯的西奥多·爱因斯坦的研究。 这项工作的目的是了解特定的有机分子如何将直径为5 nm的开放孔组合成大的常规蜂窝图案。 为了探索这种行为的一般性，巴特尔将与爱因斯坦的理论计算一起在不同的分子和底物材料上进行实验，这些实验试图用氢键和大孔来解释短距离结构，并以底物的电子结构来解释较大的孔。 通过指挥交互机制，Bartels和Einstein将寻求设计开放孔的大小，也可能是分子网络的模式。 这样的表面可以用作模板，用于在储存技术到异质催化的应用上种植图案膜的模板。 教育益处包括在原子量表进行成像的最先进技术和模拟系统中对研究生的培训和博士后伙伴，在这些技术中，相对较小的能量和微妙的效果决定了整体几何形状。 这也是基于物理理论与基于化学的实验之间协同和紧密合作的重要机会，为参与的学生提供了高度跨学科的培训。
