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.

这个GOALI奖由无机，生物无机和有机化学计划在化学部，材料研究部和数学与物理科学理事会多学科活动办公室的固态化学计划支持合作学术/由罗切斯特大学的理查德·艾森伯格教授和伊士曼柯达公司领导的工业小组，研究重金属络合物的发光，它们作为发射体结合到OLED器件中。 掺杂剂发射体用于有机发光二极管（OLED）材料中，以使其对于显示器应用更高效和通用。 发光重金属配合物通过三重激发态（激子）发光，提供了比单独的有机聚合物材料更高效率的途径。 将制备几类金属络合物，包括正方形平面铱和铂系统以及多核金属络合物，并通过其配体的变化来调节其物理性质。 这些配合物的发射量子产率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配合物包括Au（I）和Cu（I）配合物以及面对面的正方形平面系统。 新的复合物将通过掺入原型OLED设备中进行检查，并在操作条件下进行光致发光和稳定性分析。 选定的掺杂剂发射体将被调查，以他们的激发机制和限制其效率的因素，以确定分子性质的改变，提高OLED显示器的性能。工业伙伴关系还将包括一系列互惠研讨会，其中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。 这些研究人员还将开发一个关于光化学和显示设备的演示和教学单元，供中小学使用。 该单位还将与罗切斯特博物馆和科学中心共享，以进行公开展示。 与美国化学学会罗切斯特分会合作，将发起一个工业指导伙伴关系的试验计划，罗切斯特大学的本科生和研究生将在柯达公司得到一名工业指导，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。 为学生提供工业环境中的教育机会，并将向当地学校和博物馆提供教育示范单位。
