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.

化学系无机、生物无机和有机化学项目的GOALI奖支持由罗切斯特大学的Richard Eisenberg教授、加州理工学院的Jonas Peters教授和伊士曼柯达公司的科学家领导的学术/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OLED（有机发光二极管）器件的金（I）和铜（I）配合物。这些离子的络合物通常在室温下具有明亮的固态光电发射。 在所研究的Au（I）体系中，新的三核配合物将被合成，一系列发射性的双核Au（I）配合物将被修饰，以达到整体电荷中性和结构完整性的双重目标。这两个特征都被认为是基于气相沉积的器件结合所必需的。发光的单核和双核Cu（I）配合物，包括中性双核Cu（I）配合物具有金刚石核心结构和单核Cu（I）系统与扭曲的四面体几何形状也将被检查。进一步的工作，以阐明配体的变化如何影响这些和相关的配合物中的发射将进行，使配合物的发射特性可以系统地修改。新系统将被整合到原型OLED设备中，并在工作条件下进行电致发光和稳定性测试。对于选定的掺杂剂发射体的机制，他们被激发和限制其效率的因素将进行调查。这些信息将用于识别分子性质的改变，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材料的效率。本科生、研究生和博士后将参与该项目。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。
