项目摘要

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.

在21世纪，展示发挥着核心作用。它们几乎嵌入到每一种电子设备中，很难想象没有手机、显示器和电视的世界会是什么样子。推动显示器普及的是破坏性有机发光二极管(OLED)技术。然而，最先进的真空沉积OLED存在一些结构上的弱点。这些措施包括在该装置的材料中使用稀有金属，以及依赖耗能和昂贵的真空沉积制造方法。需要解决方案，使这些设备从材料选择到制造工艺都更可持续。欧洲博士培训网络TADF解决方案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，以提高溶液处理有机发光二极管的器件性能。这10名博士科学家将进行多学科研究，以迎接这一设计挑战。尽管价格便宜，但目前最好的溶液处理有机电致发光器件(SP-OLED)仍然依赖稀有的贵金属基磷光发射体，与真空沉积OLED相比性能不佳。从定制的有机热激活延迟荧光发射体材料开始，SP-OLED的性能将基于改进的电荷传输、薄膜处理技术和器件结构的预测模型而最大化。不仅要有效地培训外勤部，而且要实现各项目标，就需要采取紧密联系的办法。TADF解决方案网络由8名欧洲顶尖学者、3家公司和5家国际合作伙伴组成，他们不仅具备应对材料和器件设计挑战的能力和经验，而且提供强大的多学科和跨部门培训环境，以确保DFS拥有进入就业市场所需的软技能和技术技能，并为确保欧洲在OLED材料领域的领先地位做出贡献。
