Out of these molecules, 17,000 could be 3D modeled, and then after large-scale screening, 50 promising candidates were selected for higher-level quantum chemical calculations. Finally, the two most promising molecules were selected to be synthesized and tested in actual OLED devices.<\/p>\n<p>\u00a0<\/p>\n<p>The two molecules Cz-PAH-1, and Cz-PAH-2, exhibited narrow bandwidths blue emission, with photoluminescence quantum yields close to 100%.
