The Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division supports the project by Professor Matthew Zimmt in the Department of Chemistry at Brown University. Professor Zimmt is developing methods to prepare patterned molecular films. Each patterned sheet is used as a high-resolution template to assemble objects, polymers, and biological molecules into a patterned array. This process generates fields of molecules regularly distributed across a surface. The potential uses of these surfaces include converting solar energy into electricity. Research students involved in this project receive broad training in interdisciplinary science. The public is engaged through the production and circulation of animated videos that introduce self-assembly and its relevance to modern life. Undergraduate art majors and science majors, the Brown Science Center, and Brown faculty collaborate to produce these videos, which are distributed through various platforms.Professor Zimmt is investigating strategies for preparing patterned, multi-component, self-assembled monolayers with unit cell repeats extending to 40 nanometers (nm), and with spatially patterned chemical reactivity on a less than 10 nanometer length scale. Methods to cross-link and stabilize these films are developed. In order to study these films, laser desorption-ionization, time-of-flight mass spectrometry is developed as a tool to investigate the assembly, composition, and reactions of physisorbed self-assembled monolayers on graphite and other conductive surfaces. Professor Zimmt integrates the research outcomes into the education of undergraduate and graduate students at Brown University. Through collaboration with the Brown Science Center, the project team produces an animated video introducing self-assembly and its relevance to daily life. This self-assembly video is being distributed online and through other media platforms.

化学学部的大分子、超分子和纳米化学项目支持布朗大学化学系的Matthew Zimmt教授的项目。zimt教授正在研究制备分子膜的方法。每个图案化的薄片用作高分辨率模板，将物体、聚合物和生物分子组装成图案化的阵列。这个过程产生了分子场，分子场在表面上有规律地分布。这些表面的潜在用途包括将太阳能转化为电能。参与该项目的研究生接受跨学科科学的广泛训练。公众通过制作和传播动画视频来参与其中，这些视频介绍了自我组装及其与现代生活的相关性。本科艺术专业和理科专业的学生、布朗科学中心和布朗大学的教职员工合作制作了这些视频，并通过各种平台分发。Zimmt教授正在研究如何制备具有图案、多组分、自组装的单层膜，其单细胞重复序列延伸至40纳米（nm），并且在小于10纳米的长度尺度上具有空间图案的化学反应性。研究了交联和稳定这些膜的方法。为了研究这些薄膜，激光解吸电离、飞行时间质谱技术被开发出来，作为一种工具来研究物理吸附自组装单层在石墨和其他导电表面上的组装、组成和反应。zimt教授将研究成果整合到布朗大学的本科生和研究生教育中。通过与布朗科学中心的合作，项目团队制作了一个动画视频，介绍自组装及其与日常生活的关系。这个自组装视频正在网上和其他媒体平台上传播。
