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.

有机灯发射二极管是固态照明设备，目前在智能手机显示器，超薄且弯曲的电视显示器和新兴的照明产品中找到，例如台灯，灯光名片和可穿戴照明作为防护磨损。目前，OLEDS的制造成本升高，这导致了昂贵的产品，市场渗透缓慢。为了降低制造成本，需要减少制造时间。通过小有机分子的热蒸发制造的OLEDS：蒸发速度越快，生产速度越快。不幸的是，几个商业分子的降解温度较低，这限制了沉积速率。该项目的目的是开发对升高沉积速率的分子家族，同时保持所需的最佳和电性能。 Lessard Group将开发OTI Lumionics将在其工业制造设施中集成到OLED的新分子家族。 OTI Luminoics的反馈将帮助Lessard组设计新分子，而OTI Lumionics则将进一步表征。这种合作伙伴关系将导致发展高度稳定和高性能的分子，这些分子将融入商业OLED。最后，我们将作为该培训计划的一部分培训高素质的人员，该计划将包括专业有机化学，化学工程和规模规模的宝贵技能，实验设计以及对有机电子的开发和表征的整体理解，该领域目前在加拿大和全球范围内开发。从该NSERC CRD研究计划中获得的应用知识不仅对安大略省的行业有益，而且对整个加拿大都有益。
