New Families of Molecules and Designed Interactions for Supramolecular Assembly

在这个由化学系的大分子、超分子和纳米化学项目资助的项目中，洛杉矶的加州大学的Paul韦斯将研究支撑重要表面化学和工程的基本表面基质-分子相互作用。 该方法是合成，制备和表征笼硫醇，具有有限的构象自由度的自组装单分子膜（SAMs），制备双功能笼分子的自组装单分子膜和研究它们的横向相互作用和基本反应性，并映射金属表面上的噻吩等不对称分子所经历的表面电位。 更广泛的影响包括培养本科生、研究生和博士后研究人员，通过出版物和在全国会议上的演讲传播研究成果，并通过与四年制大学建立合作关系来加强研究基础设施，这项工作将推进我们关于分子如何与表面相互作用的原子级基础知识。 拟议的工作可能会对纳米科学、纳米技术、电子材料和器件等领域产生重大影响，并可能为从微电子到催化化学品制造等行业带来创新。

In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Paul Weiss of the University of California at Los Angeles will study fundamental surface substrate-molecule interactions that underpin important surface chemistries and engineering. The approach is to synthesize, prepare and characterize self-assembled monolayers (SAMs) of cage thiols that have limited degrees of conformational freedom, to prepare SAMs of bifunctional cage molecules and study their lateral interactions and fundamental reactivities, and to map the surface potentials experienced by asymmetric molecules such as thiophenes on metal surfaces. The broader impacts involve training undergraduate students, graduate students, and postdoctoral researchers, disseminating research results through publications and presentations at national conferences, and enhancing research infrastructure through establishing collaborations with four-year colleges.This work would advance our fundamental, atomic scale knowledge about how molecules interact with surfaces. The proposed work could have significant impacts on the fields of nanoscience, nanotechnology, and electronic materials and devices and could generate innovations for industries ranging from microelectronics to catalytic chemical manufacturing.
