The objective of this research project, carried out by Professor Gary Blanchard and his coworkers at Michigan State University, is to develop ways to control the density and distribution of reactive functional groups at interfaces. A synthetic approach using polymeric molecular layers is used to control the density and distribution of interface functionalities. Optical probes, including picosecond lifetime measurements, molecular reorientation and isomerization measurements, and surface second harmonic generation intensity and imaging measurements are used to characterize the synthesized interfaces. With the support of the Analytical and Surface Chemistry Program, the results of this research provide an enabling foundation for future understanding of the chemistry of structurally complex surfaces. Synthesis and characterization of complex interfaces is the focus of this research project carried out with Analytical and Surface Chemistry Program support. Polymeric synthetic approaches coupled with state of the art optical characterization provides detailed fundamental information about the distribution, type, and density of chemical functionalities at these complex interfaces.

该研究项目由密歇根州立大学的加里布兰查德教授和他的同事进行，目的是开发控制界面活性官能团的密度和分布的方法。 使用聚合物分子层的合成方法用于控制界面功能的密度和分布。 光学探针，包括皮秒寿命测量，分子的重取向和异构化测量，和表面二次谐波产生强度和成像测量被用来表征合成的接口。 在分析和表面化学计划的支持下，这项研究的结果为未来理解结构复杂表面的化学提供了一个有利的基础。复杂界面的合成和表征是本研究项目的重点，该项目得到了分析和表面化学项目的支持。 聚合物合成方法与最先进的光学表征相结合，提供了有关这些复杂界面处化学官能团的分布、类型和密度的详细基本信息。
