该奖项由化学部的无机、生物无机和金属有机化学项目、材料研究部的固态化学项目以及数学和物理科学局的多学科活动办公室颁发，支持由罗切斯特大学的Richard Eisenberg教授和伊士曼柯达公司领导的合作学术/工业小组的研究，以研究重金属络合物的发光及其作为发射体融入OLED设备。掺杂剂发射体用于有机发光二极管(OLED)材料中，以使其在显示应用中更加高效和多样化。发光重金属络合物通过三重激发态(激子)发光，提供了一条比有机聚合物材料更高效率的途径。我们将制备几类金属络合物，包括方形、平面的Ir和铂体系以及多核金属络合物，并通过改变它们的配体来调节它们的光物理性质。这些配合物的发射量子产额和寿命将在刚性介质中进行研究。计算研究将提出支持和指导实验工作的趋势。具有金属中心激发态的络合物包括Au(I)和Cu(I)络合物以及面对面的正方形平面体系。新的络合物将被纳入到OLED原型器件中进行检查，并在操作条件下测试光致发光和稳定性。选定的掺杂剂发射体将被研究其激发机制和限制其效率的因素，以确定提高OLED显示器性能的分子性质变化。这种学术和产业合作还将包括一个互惠的研讨会系列，来自罗切斯特大学的人员将在柯达研究实验室举办研讨会，工业人员将在罗切斯特大学介绍他们的工作。这些研究人员还将开发一个关于光化学和显示设备的示范和教学单位，供向中小学介绍。该单元还将与罗切斯特博物馆和科学中心共享，用于公开展示。与美国化学学会罗切斯特分会合作，将启动一项工业导师伙伴关系试点计划，罗切斯特大学的本科生和研究生将在柯达公司有一名工业导师。将研究新的金属络合物，以提高用作电子设备发光显示器的材料的效率。将为工业环境中的学生提供教育机会，并将向当地学校和博物馆提供教育示范单位。

This GOALI award by the Inorganic, Bioinorganic and Organometallic Chemistry program in the Division of Chemistry, the Solid State Chemistry program in the Division of Materials Research and the Office of Multidisciplinary Activities in the Directorate of Mathematics and Physical Sciences supports research by a collaborative academic/industrial group headed by Professor Richard Eisenberg at the University of Rochester and the Eastman Kodak Company to study the luminescence of heavy metal complexes and their incorporation as emitters into OLED devices. Dopant emitters are used in organic light-emitting diode (OLED) materials to make them more efficient and versatile for display applications. Luminescent heavy-metal complexes emit light through triplet excited states (exicitons) providing a route for higher efficiency than organic polymeric materials alone. Several classes of metal complexes including square planar iridium and platinum systems and polynuclear metal complexes will be prepared and their photophysical properties tuned through variations in their ligands. The emission quantum yields and lifetimes of these complexes will be studied in rigid media. Computational studies will suggest trends to support and direct the experimental work. Complexes with metal centered excited states include Au(I) and Cu(I) complexes as well as face-to-face square planar systems. New complexes will be examined by incorporation into prototype OLED devices and assayed for photoluminescence and stability under operating conditions. Selected dopant emitters will be investigated as to their excitation mechanisms and the factors limiting their efficiency in order to identify molecular property alterations that improve performance in OLED displays.This academic-industrial partnership will also involve a reciprocal seminar series in which personnel from the University of Rochester will present seminars at the Kodak Research Laboratories and industrial personnel will present their work at the University of Rochester. These researchers will also develop a demonstration and teaching unit on photochemistry and display devices for presentation to elementary and secondary schools. The unit will also be shared with the Rochester Museum and Science Center for public presentations. In collaboration with the Rochester Section of the American Chemical Society, a pilot program for an Industrial Mentor Partnership will be initiated in which undergraduate and graduate students at the University of Rochester will have a industrial mentor at the Kodak Company.New metal complexes will be studied to improve the efficiency of materials used as light emitting displays in electronic devices. Educational opportunities for students in an industrial setting are involved and educational demonstration units will be provided to local schools and museums.
