Surface Chemistry of Functional Materials

在化学学部有机和大分子化学项目的支持下，普林斯顿大学的Jeffrey Schwartz教授和Steven Bernasek教授及其合作者将开发出在有机材料和功能表面之间创建稳定界面的新方法。这一重要的研究领域目前引起了相当大的兴趣。除了有助于对各种有机和无机材料表面化学的基本理解外，该研究还具有基于具有定制特性的界面的新技术的潜力。利用新发现的一类自组装单层有机膦酸盐（SAMP），研究人员将继续阐明功能生物材料和电子材料的表面有机化学，目标是学习如何适应离散复杂和SAMP程序，以赋予目标底物所需的特性。具体而言，该研究将(1)表征氧化铟锡（ITO）和硅上氧化层上掺杂的界面膦酸盐膜的电子结构，以更好地了解器件行为；(2)在薄膜晶体管（TFT）发展的背景下，利用SAMPs的结构基序实现有机半导体的成核生长；(3)在TFT平台上设计有序的有机物三维阵列，并以此为基础研究器件行为；(4)探索用作生物材料的有机聚合物的表面化学，其中聚合物的官能团将用于锚定改变性能的取代基；(5)发展掺杂硅器件的基础表面科学，以制备用于检测全细胞或大分子病原体的电寻址传感器。有机和大分子化学项目支持普林斯顿大学教授Jeffrey Schwartz和Steven Bernasek的研究，这些研究有可能为有机电子、生物材料和生物传感器等领域的技术发展做出贡献。该研究为培养学生提供了极好的机会，与加拿大和欧洲的电子和生物技术研究小组的紧密合作是学生的另一个优势。参与项目的研究生将接触到化学、物理、生物、材料科学和工程领域的跨学科研究。

With the support of the Organic and Macromolecular Chemistry Program in the Chemistry Division, Professors Jeffrey Schwartz and Steven Bernasek of Princeton University and their collaborators will develop new methods for creating stable interfaces between organic materials and functional surfaces. This important area of research is of considerable current interest. In addition to contributing to a fundamental understanding of the surface chemistry of a variety of organic and inorganic materials, the research has the potential to enable new technologies based on interfaces with tailored properties. Using a newly discovered class of self-assembled monolayer organophosphonates (SAMPs), the researchers will continue to elucidate the surface organic chemistry of functional biomaterials and electronic materials with the goal of learning how to adapt discrete complex and SAMP procedures to impart desirable properties to target substrates. Specifically, the proposed research will (1) characterize the electronic structure of the doped interfacial phosphonate film species on indium tin oxide (ITO) and on oxide layers on silicon to better understand device behavior; (2) use structural motifs of SAMPs to nucleate growth of organic semiconductors in the context of thin-film transistor (TFT) development; (3) design ordered three-dimensional arrays of organics on TFT platforms and study device behavior based on them; (4) explore the surface chemistry of organic polymers of use as biomaterials, where functional groups of the polymer will be used to anchor property-altering substituents; and, (5) develop the fundamental surface science of doped silicon devices to prepare electrically addressable sensors for use in detecting whole cell or large molecule pathogens.The Organic and Macromolecular Chemistry Program supports the research of Professors Jeffrey Schwartz and Steven Bernasek of Princeton University that has the potential to contribute to technology development in areas such as organic electronics, biomaterials and biosensors. The research offers an excellent opportunity for training students and the strong collaborations with research groups in Canada and Europe in electronics and biotechnology is another advantage for students. Graduate students working on the projects will be exposed to interdisciplinary research at the boundaries of chemistry, physics, biology, materials science and engineering.
