Elena Galoppini of Rutgers University at Newark, Gerald Meyer of Johns Hopkins University and Piotr Piotrowiak of Rutgers University at Newark, are supported by a NIRT grant (Nanoscience Interdisciplinary Research Teams) for their interdisciplinary effort to improve our fundamental understanding of electronic interactions at organic molecule-nanoparticle interfaces and to allow us to control them in a predictable manner. The research employs synthetic methodologies that allow control over the distance and orientation of surface bound organic molecules with respect to the nanoparticle surface. The materials that will be prepared will enable these researchers to probe long-standing fundamental questions concerning interfacial electronic interactions in molecular detail that was not previously possible. Experiments will be carried out in which the position of redox and photo-active organic compounds relative to a nanoparticle surface will be fixed to control and tune the interfacial electronic interactions through systematic molecular-level variation of surface-attached dyes and nanoparticle materials. The preparation of assemblies of molecular components (supramolecular structures) that perform desired functions such as light harvesting antennas or fluorescent sensors is a significant long term research goal. This research will probe interfacial interactions between semiconductor nanoparticles and attached molecular species. The research will contribute to our fundamental understanding of electronic interactions occuring at the interfaces between semiconductor nanoparticles and attached molecular species in order that we might control them in a predictable manner. Graduate students, undergraduate students and postdocs will receive excellent training and research experiences in a forefront nanoscience research program.

纽瓦克罗格斯大学的Elena Galoppini、约翰霍普金斯大学的Gerald Meyer和纽瓦克罗格斯大学的Piotr Piotrowiak得到了NIRT(纳米科学跨学科研究团队)的支持，以表彰他们所做的跨学科努力，以提高我们对有机分子-纳米颗粒界面上的电子相互作用的基本理解，并使我们能够以可预测的方式控制它们。这项研究使用了合成方法，允许控制表面结合的有机分子相对于纳米颗粒表面的距离和方向。即将准备的材料将使这些研究人员能够以分子细节探索与界面电子相互作用有关的长期存在的基本问题，这在以前是不可能的。将进行实验，其中氧化还原和光活性有机化合物相对于纳米颗粒表面的位置将被固定，以通过表面附着的染料和纳米颗粒材料的系统分子水平的变化来控制和调节界面电子相互作用。制备具有所需功能的分子组件(超分子结构)组件，如捕光天线或荧光传感器，是一个重要的长期研究目标。这项研究将探索半导体纳米颗粒与附着的分子物种之间的界面相互作用。这项研究将有助于我们从根本上理解半导体纳米粒子与附着的分子物种之间的界面上发生的电子相互作用，以便我们可以以可预测的方式对其进行控制。研究生、本科生和博士后将在最前沿的纳米科学研究计划中获得出色的培训和研究经验。
