The winning project is entitled: “Synthesis of novel class of organic emitters for TADF OLED materials embracing curved nanographene fragments”. Commercially used emitters in OLED materials consist mainly of noble metal complexes. The methods for obtaining them are environmentally unfriendly, the complexes are expensive and exhibit poor operational stability. Thus, many efforts are being made to use thermally activated delayed fluorescence (TADF) light emitting organic molecules as effective and readily available emission layers for OLED devices. The quantum efficiency of the emitters depends on several, often contradictory, photophysical parameters. The previously designed and tested organic molecules were oriented towards improving only one or two parameters. Therefore, the rational design of the structural motif allowing for the simultaneous improvement of all parameters remains a big challenge. The main goal of the project is to develop an efficient and inexpensive methodology for the synthesis of curved, heteroatom-doped nanographene molecules. These are designed in a way that allows for the simultaneous improvement of all parameters within one structural motif. Nanographenes will be used as emission layers in TADF OLED devices.
