The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase I project is the development of printable electron transport layer (PrETL) materials to greatly simplify the production of organic light emitting diodes (OLEDs) and significantly lower their manufacturing cost. OLEDs are found in an increasingly broad range of commercial products, such as televisions, portable devices, automotive lighting, flexible luminaries, and displays. Current commercial OLED manufacturing technologies typically require methods that are expensive, energy intensive, and slow. The biggest barrier preventing the transition from thermal evaporation to printable technologies has been a lack of commercially available printable electron transport layers. The adoption of PrETL technology will allow manufacturers to eliminate the thermal evaporation steps and enable fully-printed OLEDs at a fraction of the cost of current devices. This development will spur further penetration of OLEDs throughout the lighting and display market, providing the benefits of improved energy-efficiency, reduced eye-strain, flexible forms, minimal heat production, and lower cost device.This Small Business Innovation Research (SBIR) Phase I project addresses the lack of efficient, long-lifetime, printable electron transport layers (PrETLs) for organic light emitting diodes (OLEDs). The objectives of this project are to demonstrate the feasibility of PrETLs and PrETL-enabled, fully printed OLEDs. The innovative PrETLs developed here rely on a solution processable hexacoordinate silicon-based scaffold, that can be synthetically tuned to the electronic and material needs of the manufacturer. The Phase I project will develop PrETL thin films for material and electronic testing and for building prototype OLEDs enabled by PrETLs. The ultimate anticipated outcome of the proposed Phase I research will be a fully printed PrETL-enabled OLED with an external quantum efficiency greater than 10% and a lifetime of 10,000 hours at 1,000 nit brightness.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小企业技术转让（STTR）第一阶段项目的更广泛的影响/商业潜力是开发可印刷电子传输层（PrETL）材料，以大大简化有机发光二极管（OLED）的生产并显着降低其制造成本。 OLED在越来越广泛的商业产品中被发现，例如电视机、便携式设备、汽车照明、柔性发光体和显示器。 目前的商业OLED制造技术通常需要昂贵、能源密集且缓慢的方法。阻止从热蒸发技术过渡到可印刷技术的最大障碍是缺乏可商购的可印刷电子传输层。采用PrETL技术将使制造商能够消除热蒸发步骤，并以当前设备成本的一小部分实现完全印刷的OLED。 这一发展将刺激OLED在整个照明和显示市场的进一步渗透，提供提高能源效率，减少眼睛疲劳，灵活的形式，最小的热量产生和更低的成本设备的好处。这个小企业创新研究（SBIR）第一阶段项目解决了缺乏有效的，长寿命的，可印刷的电子传输层（PrETL）的有机发光二极管（OLED）。该项目的目标是证明PrETL和PrETL启用的全印刷OLED的可行性。 这里开发的创新PrETL依赖于可溶液加工的六配位硅基支架，可以根据制造商的电子和材料需求进行综合调整。第一阶段项目将开发用于材料和电子测试的PrETL薄膜，并用于构建由PrETL实现的原型OLED。 第一阶段研究的最终预期成果将是一个完全印刷的PrETL功能OLED，其外部量子效率大于10%，在1，000尼特亮度下的寿命为10，000小时。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
