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，目前用于智能手机显示屏、超薄曲面电视显示屏以及台灯、发光名片和作为防护服的可穿戴照明等新兴照明产品。目前，OLED的制造成本升高，导致产品价格昂贵，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：蒸发速率越快，生产速度就越快。不幸的是，一些商业分子的降解温度较低，这限制了沉积速率。该项目的目标是开发耐热性较高的沉积速率的分子家族，同时保持所需的最佳性能和电性能。 Lessard 集团将开发一系列新分子，OTI Lumionics 将在其工业制造工厂中将这些分子集成到 OLED 中。 OTI Luminoics 的反馈将帮助 Lessard 小组设计新分子，而 OTI Lumionics 又将进一步对其进行表征。此次合作将促进高度稳定和高性能分子的开发，并将其集成到商用 OLED 中。最后，作为该培训计划的一部分，我们将培训高素质人才，其中包括专业有机化学、化学工程和放大、实验设计以及对有机电子学（这一领域的发展和表征）的整体理解的宝贵技能。目前在加拿大和世界各地蓬勃发展。从 NSERC CRD 研究项目中获得的应用知识不仅有利于安大略省的工业，而且有利于整个加拿大。
