STTR Phase I: Robust Organic Light-Emitting Diodes (OLED) Displays using Self-Assembled MonoLayers

小型企业技术转移（STTR）第一阶段项目将展示使用自组装单层大幅提高OLED显示器性价比的可行性。OLED行业对p-i-n结构OLED感兴趣，因为它们可以通过使用空气稳定的可印刷电极在露天条件下在柔性屏障基板上完全印刷；然而，这些显示器受到切换速度慢和寿命缩短的影响。该方案的智力优势集中在使用自组装单层（SAM）稳定OLED器件的p-i-n结结构。这项工作将侧重于开发用于沉积SAM层的材料和工艺，特别是克服当前p-i-n显示器的弱点，这些弱点是由p和n型掺杂剂的迁移性引起的，并显著提高LEP器件在柔性基板上的效率、寿命、开关速度和可印刷性。该提案的更广泛影响将是创建一个重要的技术和基于印刷的制造平台，这将加速OLED显示器和光伏在低成本，大面积光电市场的使用。这种技术有望提供低成本、灵活的显示器，并可能对其他可印刷电子产品产生直接影响，如有机晶体管和存储器，在这些领域，低成本制造高效率设备对商业成功至关重要。

The Small Business Technology Transfer (STTR) Phase I project will demonstrate the feasibility of using self-assembled mono-layers to dramatically improve the cost performance of OLED displays. The OLED industry is interested in p-i-n structured OLEDs because they can be fully printed in open-air conditions on flexible barrier substrates through the use of air-stable printable electrodes; however, these displays suffer from slow switching speeds and shortened lifetimes. The intellectual merit of this proposal is focused on stabilizing the p-i-n junction architecture for OLED devices using self-assembled mono-layers (SAM). This effort will focus on developing the materials and processes for depositing the SAM layer that specifically overcomes the weaknesses of current p-i-n displays caused by the mobility of the dopants responsible for the p and n-type doping, and to dramatically improve the efficiency, lifetime, switching speed, and printability of LEP devices onto flexible substrates. The broader impact of this proposal will be the creation of a significant technology and print-based manufacturing platform that will accelerate the use of OLED displays and photovoltaics in the low cost, large-area optoelectronic markets. Such technology is expected to provide low cost, flexible displays and could have a direct impact on other printable electronics, such as organic transistors and memory, where low cost manufacturing of high efficiency devices are paramount for commercial success.
