9612281 Sturm The PI's propose an interdisciplinary program to investigate the critical issues currently confronting developments in the new and very promising field of polymer-based organic light emitting devices (OLEDs). Red, green and blue emitting OLEDs have recently gained worldwide attention due to their promise for revolutionizing the flat panel display industry. Before these devices can be used in practical low cost displays, however, many problems of fundamental as well as of a practical nature must be addressed and solved. Among the most important issues, which are the subject of the proposed investigations, are: (i) thickness and compositional control of the light emitting and charge-transporting thin films; (ii) control and reduction of impurity incorporation into the films, as well as assessment of the effects of impurities on OLED performance, (iii) understanding and control of electron and excitor transport across organic/organic and organic/metal interfaces, (iv) improvement of device reliability, and (v) device processing and integration. We have assembled a multidisciplinary team of researchers from the Departments of Chemistry, Chemical, and Electrical Engineering at Princeton University and the University of Southern California with a long term track record of collaboration for making fundamental advances in the field of OLEDs. We will apply a range of novel concepts and experimental methods to address all four of these key issues to the study of polymer/polymer, polymer/small molecule, and organic/metal interfaces and devices. We anticipate that the impact of this work will extend well beyond OLED science and technology, into the field of a wide range of active polymeric and small molecular organic heterojunction devices such as transistors and solar cells. ***

9612281 Sturm PI提出了一项跨学科计划，以调查目前在新兴且非常有前途的聚合物基有机发光器件（oled）领域发展面临的关键问题。红、绿、蓝三色发光oled因其革命性的平板显示产业而受到全球关注。然而，在这些器件可以用于实际的低成本显示器之前，许多基本的和实际性质的问题必须被处理和解决。其中最重要的问题，这是提出的研究的主题，是：(i)厚度和组成控制的发光和电荷传输薄膜；（ii）控制和减少杂质进入薄膜，以及评估杂质对OLED性能的影响，（iii）理解和控制电子和激子在有机/有机和有机/金属界面上的传输，（iv）提高设备可靠性，以及(v)设备加工和集成。我们已经组建了一个由普林斯顿大学化学系、化学系和南加州大学电气工程系的多学科研究人员组成的团队，他们长期合作，在oled领域取得了根本性的进步。我们将运用一系列新颖的概念和实验方法来解决所有这四个关键问题，以研究聚合物/聚合物，聚合物/小分子，有机/金属界面和器件。我们预计这项工作的影响将远远超出OLED科学和技术，进入广泛的活性聚合物和小分子有机异质结器件领域，如晶体管和太阳能电池。＊＊＊
