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.

小企业技术转让（STTR）第一阶段项目将展示使用自组装单层显着提高OLED显示器的性价比的可行性。 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户外条件下完全印刷在柔性屏障基板上;然而，这些显示器遭受缓慢的切换速度和缩短的寿命。该建议的智力价值集中在使用自组装单层（SAM）稳定OLED器件的p-i-n结结构。这项工作将集中于开发用于沉积SAM层的材料和工艺，该SAM层特别克服了由负责p型和n型掺杂的掺杂剂的迁移率引起的当前p-i-n显示器的弱点，并显著提高LEP器件在柔性基板上的效率、寿命、切换速度和可印刷性。这一提议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显示器和光电子器件在低成本、大面积光电市场的使用。这种技术有望提供低成本的柔性显示器，并可能对其他可印刷电子产品（如有机晶体管和存储器）产生直接影响，其中高效率器件的低成本制造对于商业成功至关重要。
