Organic Light Emitting Diodes are solid-state lighting devices that are currently found in smart phone displays, ultra thin and curved television displays and emerging lighting products like desk lamps, light-up business cards and wearable lighting as protective wear. Currently, the manufacturing cost of OLEDs is elevated which leads to expensive products with a slow penetration of the market. To reduce manufacturing costs, manufacturing time needs to be reduced. OLEDs aremanufactured by thermal evaporation of small organic molecules: the faster the evaporation rate, the faster the production. Unfortunately, several commercial molecules have low degradation temperatures, which limits deposition rate. The goal of this project is to develop families of molecules that are thermally resistant to elevated deposition rates while maintaining the desired optimal and electrical properties. The Lessard group will develop families of new molecules that OTI Lumionics will integrate into OLEDs in their industrial manufacturing facility. The feedback from OTI Luminoics will help the Lessard group to design new molecules, which will in turn be further characterized by OTI Lumionics. This partnership will lead to the development of highly stable and high performing molecules that will be integrated into commercial OLEDs. Finally, we will train highly qualified personnel as part of this training program, which will include valuable skills in specialized organic chemistry, chemical engineering and scale up, experimental design and a holistic understanding of the development and characterization of organic electronics, a field that is currently blossoming in Canada and worldwide. The application knowledge gained from this NSERC CRD research program will not only be beneficial for industry in Ontario, but for all of Canada.

有机发光二极管是固态照明器件，目前应用于智能手机显示器、超薄和曲面电视显示器以及新兴照明产品，如台灯、发光名片和可穿戴照明作为防护服。目前，OLED的制造成本提高，导致产品昂贵，市场渗透缓慢。为了降低制造成本，需要减少制造时间。OLED是通过有机小分子的热蒸发来制造的：蒸发速度越快，生产速度就越快。不幸的是，几种商业分子具有低降解温度，这限制了沉积速率。该项目的目标是开发分子的家庭，是耐热的提高沉积速率，同时保持所需的最佳和电气性能。Lessard集团将开发新分子家族，OTI Lumionics将在其工业制造设施中将其整合到OLED中。来自OTI Luminoics的反馈将帮助Lessard团队设计新的分子，OTI Lumionics将进一步对其进行表征。这种合作关系将导致高度稳定和高性能分子的开发，这些分子将被集成到商业OLED中。最后，我们将培养高素质的人才作为这个培训计划的一部分，这将包括专业有机化学，化学工程和规模扩大，实验设计和有机电子的发展和表征的整体理解的宝贵技能，这是目前在加拿大和世界各地蓬勃发展的领域。从NSERC CRD研究计划中获得的应用知识不仅对安大略的工业有益，而且对整个加拿大有益。
