CAREER: From Surface to Solution: Bond Scission and Templating for Fabrication of Nanoscale Structures

这个项目旨在开发使用化学图案表面作为纳米级粒子生长模板的方法。自组装单层的微接触印刷将用于固定多层材料的生长。通过切断已经合成成固定的自组装单层的容易断裂的键，这些粒子将从基材上分离出来，留下完整的化学图案表面供进一步使用——同样的机器也可以产生粒子。我们的目标还包括能够生成新的粒子形貌，并在溶液中复制粒子。最初，材料的重点将放在层状金属膦酸盐上，由堆叠的金属膦酸盐片组成，这些金属膦酸盐片由密集排列的有机柱状基团共价连接，其中分层和再生的循环可能导致纳米颗粒的指数放大，类似于生化系统中已知的过程。将研究主题与强调化学和公共政策的教育主题相结合，作为辅助材料纳入化学课程，并进行开发和测试。这种涉及材料化学基础调查的研究和教育是针对几个环境领域的技术应用来说明材料化学在实践中的应用-在工业，政府和法院-向学生展示它是如何在现实世界中使用的

Microcontact printing in a self-asssembled monolayer will be used to anchor the growth of multilayer materials. The particles will be detached from the substrate by severing easily cleaved bonds that have been synthesized into the anchoring self-assembled monolayer, leaving intact the chemically patterned surface for further use - a ditto machine for generating particles. The goal is also to be able to generate novel particle topographies and to make copies of particles in solution. Initially, the materials focus will be on layered metal phosphonates consisting of stacked sheets of metal phosphonates covalently linked by densely packed organic pillaring groups where a cycle of delamination and regrowth could lead to exponential amplification of the nanoparticles similar to processes known to occur in biochemical systems. The integration of research themes together with a focus on educational themes that emphasize chemistry and public policy for non-science majors will be developed and tested as supporting materials to be incorporated into the chemistry curriculum.%%%This research and education involving fundamental investigations of materials chemistry is directed at technological applications in several environmental areas to illustrate materials chemistry in practice - in industry, government, and the courts - to show students how it is used in the real world.***
