Solution-processed OLED lighting devices using supramolecular aggregates of pigments. Topic 8d

Compared to inorganic solid-state lighting, organic light emitting diode (OLED) based lighting devices possess several advantages. Specifically, these devices emit diffused light that is less harmful to human eyes and operate at a lower voltage and can be made large-area and of various shapes including flexible structures. These factors are important for the adoption of the new technology by the residential, commercial, and industrial lighting markets. However, solution- processed organic light-emitting materials suffer from an uncontrollable aggregation of pigments that lead to quenching of the emission signal and lower light-emission intensity. Kebotix aims to address this problem by developing organic molecules-based lighting devices that exploit the aggregation-induced emission phenomenon. By specific choice of materials, one can control the luminescence quenching and even reverse it. This effort will help to solve the luminescence quenching problem while maximizing the emission efficiency of lighting devices. Kebotix will apply its proprietary pipeline for a multi-level smart-throughput screening of organic molecules and aggregates. Specifically, we will focus on small organic molecules that are compatible with the conventional solution-processing methods of film deposition. The top candidates will be synthesized and characterized using Kebotix automated platform, then assembled into devices. The developed technology will have direct application in the design of large-scale manufacturing of organic lighting devices that are price competitive with their inorganic counterparts.
