Abstract
Series of compounds consisting of carbazole arms and 1,3,5-triazine core linked by amino group were synthesized and characterized. The clear relationship between electrochemical properties, quantum efficiency, charge transport properties and structure were estimated. The exciplex-forming properties of the synthesized compound as donor, and two known exciplex-forming acceptors 4,7-diphenyl-1,10-phenanthroline (Bphen) and 2,2′,2"-(1,3,5-benzenetriyl)-tris(1-phenyl-1-H-benzimidazole) (TPBi) where predicted and investigated. It was shown that the star-shaped configuration of the compound 3CzNCprovides the best exciplex OLED performance with EQE up to 6.84%.
