OLED pixels normally consist of multiple layers which ensure, for example, that electrons can travel in the pixel with as little resistance as possible. The fine-tuning of the layer properties, for example, electron mobility or the emitted wavelength (color of the light), is a complex task. An international team of researchers (South Korea, Ukraine, Belgium, Germany) compared a wide range of computer-simulated and experimentally measured properties of OLED thin films, trying to understand whether OLED design can be guided solely by computer. They established a molecular library of typical OLED materials to streamline the design of new molecular structures and to simulate the properties of the corresponding thin layers. They hope that the simulation protocols can be used to design molecular structures with given properties. They simulated and measured various parameters of OLED layers and found good correlations for some properties and consistent trends for others. The data (version 1.0) that support the findings of this study are openly available in GitLab of the Max Planck Computing and Data Facility… read more. Open Access TECHNICAL ARTICLE
