GOALI Program: The Study of Luminescent Metal Complexes and their Incorporation as Emitters in Electroluminescent Devices

该奖项由化学系无机、生物无机和有机金属化学项目颁发，支持由罗切斯特大学理查德·艾森伯格教授、加州理工学院乔纳斯·彼得斯教授和伊士曼柯达公司科学家领导的学术/工业合作小组的研究。目标是设计、合成和研究用于电致发光或有机发光二极管（OLED）器件的金(I)和铜(I)配合物。这些离子的配合物在室温下经常发出明亮的固态发光。在待研究的Au(I)体系中，将合成新的三核配合物，并以总体电荷中性和结构完整的双重目标对一组发射双核Au(I)配合物进行修饰。这两个特征都被认为是基于气相沉积的设备集成所必需的。还将研究发光单核和双核Cu(I)配合物，包括具有金刚石核结构的中性双核Cu(I)配合物和具有扭曲四面体几何形状的单核Cu(I)系统。进一步阐明配体变化如何影响这些和相关配合物的发射，以便系统地修改配合物的发射特性。新系统将集成到原型OLED器件中，并在操作条件下分析电致发光和稳定性。对于选定的掺杂发射体，将研究其激发机制和限制其效率的因素。这些信息将用于识别分子特性的改变，从而提高OLED材料和显示器的性能。从手机和手持设备到笔记本电脑和电视的平板显示器代表了一个巨大的经济增长领域。本项目开发的新型金属配合物将用于提高电子设备中发光显示器材料的效率。本项目将招收本科生、研究生和博士后。学生将与工业化学家进行互动，从而扩大他们的教育和培训的范围和视角。

This GOALI award by the Inorganic, Bioinorganic and Organometallic Chemistry program in the Division of Chemistry, supports research by a collaborative academic/industrial group headed by Professor Richard Eisenberg at the University of Rochester, Professor Jonas Peters at the California Institute of Technology, and scientists at the Eastman Kodak Company. The goal is to design, synthesize, and study gold(I) and copper(I) complexes for use in electroluminescent or OLED (organic light-emitting diode) devices. Complexes of these ions are often luminescent with bright solid state photoemission at room temperature. Among Au(I) systems to be studied, new trinuclear complexes will be synthesized and a set of emissive dinuclear Au(I) complexes will be modified with the dual objectives of overall charge neutrality and structural integrity. Both of these features are deemed necessary for device incorporation based on vapor deposition. Luminescent mono- and dinuclear Cu(I) complexes including a neutral dinuclear Cu(I) complex having a diamond-core structure and mononuclear Cu(I) systems with distorted tetrahedral geometries will also be examined. Further work to elucidate how ligand variation influences the emission in these and related complexes will be conducted so that the emission characteristics of the complexes can be systematically modified. The new systems will be incorporated into prototype OLED devices and assayed for electroluminescence and stability under operating conditions. For selected dopant emitters the mechanisms by which they are excited and the factors limiting their efficiency will be investigated. This information will be used to identify molecular property alterations that produce improved performance in OLED materials and displays. Flat panel displays from cellphones and hand-held devices to lap-top computers and televisions represent a tremendous economic growth area. The new metal complexes developed in this project will be studied to improve the efficiency of materials used as light emitting displays in electronic devices. Undergraduate, graduate, and postdoctoral students will be involved in this project. The students will have interactions with industrial chemists, thus expanding the scope and perspective of their education and training.
