The focus of this research is to functionalize nanoparticles, eliminate aggregation of the resulting particles, segregate and assemble the particles in polymer materials, and explore the chemistry of the functionalized particles at liquid-liquid interfaces. The goal of the project is to achieve precise interfacial control of the nanoparticles within polymer matrices by the simultaneous use of tri-n-octyl phosphine oxide (TOPO) to control solubility, and ruthenium-based Grubb's catalyst sites to initiate polymerization in a spacially segregated manner. A second aspect of the proposed work involves orienting the nanoparticles along an aqueous-organic phase boundary. Unique educational opportunities for students will be pursued in collaboration with scientists from Kodak. With this CAREER award, the Organic and Macromolecular Chemistry Program is supporting the research and educational efforts of Dr. Todd Emrick of the Department of Chemistry at the University of Massachusetts, Amherst. Professor Emrick will focus his research on the development of new materials containing nanoparticles oriented along specific planes within the materials. This could have important ramifications in the development of new types of optical and electrical devices. The educational activities of the award will include interactions of his students with scientists at Kodak Park in Rochester, New York.

本研究的重点是功能化的纳米粒子，消除所产生的颗粒的聚集，分离和组装的聚合物材料中的颗粒，并探讨功能化的颗粒在液-液界面的化学。 该项目的目标是通过同时使用三正辛基氧化膦（TOPO）来控制溶解度，并使用基于铼的Grubb催化剂位点以空间隔离的方式引发聚合，从而实现聚合物基质内纳米颗粒的精确界面控制。 所提出的工作的第二方面涉及使纳米颗粒沿着水-有机相边界取向。 将与柯达的科学家合作，为学生提供独特的教育机会。 有了这个职业奖，有机和高分子化学计划是支持的研究和教育工作的托德埃姆里克在马萨诸塞州，阿默斯特大学化学系。 Emrick教授将把研究重点放在开发含有纳米粒子的新材料上，纳米粒子在材料中沿沿着特定平面定向。 这可能对新型光学和电子设备的发展产生重要影响。 该奖项的教育活动将包括他的学生与科学家在罗切斯特，纽约柯达公园的互动。
