International Collaboration in Chemistry: A New Molecular Architecture for Organic Electronics

“这项奖励是根据2009年美国复苏和再投资法案（公法111-5）资助的。”普林斯顿大学的Jeffrey Schwartz教授和Steven L. Bernasek教授在化学系分析和表面化学项目的支持下，与布伦瑞克工业大学的Marc Tornow教授和慕尼黑工业大学的Gerhard Abstreiter教授合作开展研究，开发有机电子学的新分子结构。自组装的活性有机分子单层将通过磷酸盐基团与天然或生长的SiO2的表面键合来合成。所得到的配合物然后与芳香双膦酸盐反应形成双层结构。该反应方案的多次应用导致了有序多层膜的生长。最后，这些多层将作为有源半导体元件包括在基于si - sio2的电子器件中。最终目标是将基础表面科学和界面合成化学与新型器件结构相结合，构建用于微电子器件的下一代分子尺度晶体管。这个项目让学生接触到国际研究经验，并为他们提供与德国研究人员交流的机会。该项目由美国国家科学基金会和德国研究协会（DFG）联合支持。

"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."Professors Jeffrey Schwartz and Steven L. Bernasek of Princeton University are supported by the Analytical and Surface Chemistry Program in the Division of Chemistry to conduct research in collaboration with Professor Marc Tornow of Braunschweig University of Technology, and Professor Gerhard Abstreiter of the Technical University of Munich to develop a new molecular architecture for organic electronics. Self assembled monolayers of active organic molecules will be synthesized via surface-bonding of phosphonate groups to native or grown SiO2. The resulting complex is then reacted with aromatic biphosphonates to form a bilayer structure. Multiple application of the reaction scheme results in the growth of ordered multilayers. Finally, these multilayers will be included as the active semiconducting component into Si-SiO2-based electronic devices. The ultimate goal is to integrate fundamental surface science and interface synthesis chemistry with novel device architecture to build the next generation molecular scale transistors for applications in microelectronic devices. This project exposes students to an international research experience and provides them with opportunities to network with researchers in Germany. The project is supported jointly by the NSF and the Deutsche Forschungsgemeinschaft (DFG).
