项目摘要
In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program in the Division of Chemistry, Matthew Zimmt of Brown University will study ways to stabilize physisorbed monolayers on graphite in order to enable practical uses and applications of these nanoperiodic structures. Patterning strategies to be explored include modulating electrostatic interactions between aliphatic chains bearing dipolar groups, tailored packing of alkadiyne chains, and electrostatic interactions between heteroaromatic cores of adsorbing molecules. Monolayer stabilization strategies to be tested include using extremely long aliphatic chains, polymerizing diyne side chains, and polymerizing functionalized aromatic cores. Functional groups projecting from the aromatic cores of molecules in the monolayers will be used as capture elements, enabling patterned monolayers to function as ultra-high resolution (less than 10 nm size features) planar templates for capturing polymers, nanoparticles and biomolecules. The broader impacts involve training undergraduate and graduate students, enhancing research infrastructure through hosting graduate student visitors from the Czech Technical University in Prague, and broadly disseminating research results through publications, presentations at national meetings, and software development to correct for thermal drifts in STM.One of the major challenges of modern nanochemistry is to guide very small chemical objects to assemble spontaneously into precise, useful patterns over large areas. If successful, this project will yield novel strategies for the preparation of stable, patterned templates with a thickness of one molecule and an extremely high density of binding sites. The binding site patterns will direct the assembly of many other chemical species into precise, two dimensional patterns. Ultimately, such work could lead to applications in the fields of chemical sensing, nanoscale electronics, solar energy conversion, and biomedical materials.
在这个由化学系大分子,超分子和纳米化学计划资助的项目中,布朗大学的Matthew Zimmt将研究稳定石墨上物理吸附单分子层的方法,以实现这些纳米周期结构的实际用途和应用。要探索的图案化策略包括调制脂肪族链承载偶极基团之间的静电相互作用,定制包装的烷二炔链,和吸附分子的杂芳族核心之间的静电相互作用。待测试的单层稳定化策略包括使用极长的脂肪族链、聚合二炔侧链和聚合官能化芳族核。 从单层中分子的芳香核突出的官能团将被用作捕获元件,使得图案化的单层能够用作超高分辨率(小于10 nm尺寸特征)平面模板,用于捕获聚合物、纳米颗粒和生物分子。更广泛的影响包括培训本科生和研究生,通过接待来自布拉格捷克技术大学的研究生访问者来加强研究基础设施,并通过出版物,在国家会议上的演讲,现代纳米化学的主要挑战之一是引导非常小的化学物体自发地组装成在大面积上形成精确有用的图案。 如果成功,该项目将产生新的策略,用于制备具有一个分子厚度和极高密度的结合位点的稳定的图案化模板。 结合位点模式将指导许多其他化学物质组装成精确的二维模式。最终,这些工作可能会导致在化学传感,纳米电子学,太阳能转换和生物医学材料领域的应用。
