2D Molecular Grids Made to Order

该项目旨在探索制备具有明确尺寸、形状和功能的大分子结构的新方法。具体目标是：(1)发展化学以快速合成多功能低聚构建块；(2)制备一系列[n]阶梯结构；(3)探索长度调节策略以控制和限制自组装纳米结构的生长，并测试游标镶嵌的预测；(4)合成二维分子网格。本项目将采用的方法包括先进的合成技术、动态共价自组装、分子建模和先进的表征技术。有了这个奖项，有机和大分子化学项目支持了伊利诺伊大学厄巴纳-香槟分校化学系杰弗里·s·摩尔教授的研究。摩尔教授的研究工作围绕着制备具有明确尺寸、形状和功能的大分子结构。目标结构的实现不仅将是纳米合成领域的重大成就，而且将有助于解决材料科学和生物学领域的重要问题，包括下一代纳米电子和信息存储设备、纳滤膜、纳米生物技术支架和太阳能收集网格。

This project is aimed at exploring new ways to prepare large molecular structures having well-defined size, shape, and functionality. The specific objectives are to: (1) develop chemistry to rapidly synthesize multi-functional oligomeric building blocks, (2) prepare a series of [n]-rung ladder structures, (3) explore length-regulation strategies for controlling and limiting the growth of self-assembled nanostructures and to test the predications of vernier tessellation, and (4) synthesize two-dimensional molecular grids. The methods that will be employed in this project include advance synthetic techniques, dynamic covalent self-assembly, molecular modeling, and advance characterization techniques. With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Professor Jeffrey S. Moore, of the Department of Chemistry at University of Illinois at Urbana-Champaign. Professor Moore's research efforts revolve around the preparation of large molecular structures having well-defined size, shape, and functionality. Realization of the targeted structure will not only be a significant accomplishment in nanoscale synthesis, but will also contribute to solving important problems in materials science and biology including next-generation nanoscale electronics and information storage devices, nanofiltration membranes, scaffolds for nanobiotechnology, and grids useful for solar energy harvesting.
