TADFsolutions: Addressing the challenges of high-performance solution-processed OLEDs using sustainable materials

在21世纪的世纪，显示器发挥着核心作用。它们几乎嵌入到每一种电子设备中，很难想象一个没有移动的电话、显示器和电视的世界。驱动显示器普及的是颠覆性的有机发光二极管（OLED）技术。然而，在现有技术的真空沉积OLED中存在一些结构弱点。这些问题包括在器件材料中使用稀有金属，以及依赖能源密集型和昂贵的真空沉积制造方法。需要解决方案来使这些设备从材料选择到制造工艺更具可持续性。欧洲博士培训网络TADFsolutions将培训一批充满活力的研究人员，以设计、开发和实施可持续的解决方案，提高溶液处理OLED的器件性能。10位博士科学家将进行多学科研究，以应对这一设计挑战。目前最好的溶液处理OLED（SP-OLED）尽管价格便宜，但仍然依赖于稀有的贵金属磷光发光体，与真空沉积OLED相比性能较差。从定制的有机热激活延迟荧光发光体材料开始，SP-OLED的性能将基于改进的电荷传输预测模型，薄膜处理技术和器件结构来最大化。不仅需要一种相互联系紧密的办法来有效地培训发展筹资人员，而且还需要实现这些目标。TADF解决方案网络由8位欧洲领先的学者、3家公司和5家国际合作伙伴组成，他们不仅拥有丰富的设备和经验，能够应对材料和设备设计挑战，而且能够提供强大的多学科和跨部门培训环境，以确保DF拥有必要的技能，包括软件和技术。进入就业市场，并为确保欧洲在OLED材料领域的领先地位做出贡献。

In the 21st century, displays play a central role. They are embedded in almost every type of electronic device and it is difficult to imagine a world without mobile phones, monitors and televisions. Driving the pervasiveness of displays is thedisruptive organic light-emitting diode (OLED) technology. There are, however, some structural weaknesses in state-of-theart vacuum-deposited OLEDs. These include the use of scarce metals within the materials of the device and the reliance on energy-intensive and expensive vacuum deposition fabrication methods. Solutions are required to make these devices more sustainable from choice of materials to manufacturing processes. The European Doctoral Training Network TADFsolutions will train a cohort of dynamic researchers to devise, develop and implement sustainable solutions for improving the device performance of solution-processed OLEDs. The 10 PhD scientists will undertake multidisciplinary research to meet this design challenge. Despite being cheaper, the current best solution-processed OLEDs (SP-OLEDs) still rely on scarce noble-metal-based phosphorescent emitters and underperform compared to vacuum-deposited OLEDs.Starting from bespoke organic thermally activated delayed fluorescence emitter materials, the performance of SP-OLEDs will be maximized based on improved predictive models of charge transport, film processing techniques, and devicestructures. A strongly interconnected approach is required not only to effectively train the DFs but to meet the objectives. The TADFsolutions network consists of 8 leading European academics, 3 companies, and 5 international partners that are equipped and experienced to not only confront the materials and device design challenges but to provide a robust multidisciplinary and intersectoral training environment to ensure that the DFs have the requisite skills, both soft and technical, to enter the employment market and contribute to securing Europe's leading role in OLED materials.
