This proposal was received in response to Nanoscale Science and Engineering initiative, NSF 04-043, category NER. The objective of this research is to devise strategies for the large scale assembly of functional nanostructures. The specific approach is to use electrodeposition and self-assembled molecular templates. This NER proposes the formation of long range, periodic nanoscale structures (metal and polymer) by electrodeposition in nanoscale areas defined by self-assembled molecular structures. These nanostructures and their formation will be investigated by atomic force microscopy and scanning tunneling microscopy.Questions that we will address includea) What is the effect of molecular template structure on the deposition pattern (molecular length, molecular shape and effect of end groups,)?b) What is the range of species that can be deposited (different metals, organic species that can be electrografted to the surface, )?c) Can molecular templating supplement other nanolithographic processes (nanoshaving, dip-pen nanolithography,)? The broader impact arises from the potential that controlled assembly of individual atoms and molecules on surfaces could supplement lithographic techniques in manufacturing, as nanoscale molecular engineering becomes an integral part of miniaturization in electronic and photonic devices. However, turning arrays of atoms and molecules into practical, useful supramolecular structures to be used as templates for nanostructure formation requires that a number of fundamental questions be resolved regarding the nature of the controlled assembly process. The results of this research will be of significance in those fields where the formation of functional nanostructures is important including electrocatalysis, self assembly and electrodeposition of organic and inorganic species. Broader impact of the proposed research includes the training of post-doctoral, graduate and undergraduate students, the next generation of scientists. Our group is committed to the undergraduate research experience, a central core of our group's mission to exposing students to state of the art scientific methods.

该提案是为了响应纳米科学与工程倡议，NSF 04-043，NER 类别而收到的。 这项研究的目的是设计大规模组装功能纳米结构的策略。具体做法是采用电沉积和自组装分子模板。 该 NER 提出通过在自组装分子结构定义的纳米级区域中电沉积形成长程、周期性纳米级结构（金属和聚合物）。 这些纳米结构及其形成将通过原子力显微镜和扫描隧道显微镜进行研究。我们将解决的问题包括a) 分子模板结构对沉积模式的影响是什么（分子长度、分子形状和端基的影响）？b）可以沉积的物种范围是多少（不同的金属、可以电接枝到表面的有机物种）？c）分子可以 模板补充其他纳米光刻工艺（纳米剃须、浸笔纳米光刻）？随着纳米级分子工程成为电子和光子器件小型化不可或缺的一部分，表面上单个原子和分子的受控组装可以补充制造中的光刻技术，从而产生更广泛的影响。 然而，将原子和分子阵列转变为实用的、有用的超分子结构以用作纳米结构形成的模板，需要解决有关受控组装过程的性质的许多基本问题。 这项研究的结果对于功能纳米结构的形成很重要的领域将具有重要意义，包括电催化、有机和无机物质的自组装和电沉积。拟议研究的更广泛影响包括对博士后、研究生和本科生以及下一代科学家的培训。 我们的团队致力于本科生研究经验，这是我们团队让学生接触最先进的科学方法的使命的核心。
