The authors report novel small-molecule green-fluorescent hosts for solution processed OLEDs. 9,10-Diarylanthracene and fluorene moieties were introduced to the 9 and 10 positions of an anthracene core to give the strong amorphous characteristics. These novel hosts show sufficient optical, electrical, and thermal properties with very good solubility in organic solvents. Utilizing these solution-processed hosts, a maximum current efficiency of 7.8 cd/A is demonstrated with a general fluorescent dopant.
作者报告了用于溶液处理有机发光二极管的新型小分子绿色荧光宿主。在蒽核的 9 和 10 位上引入了 9,10-二芳基蒽和芴分子,使其具有很强的无定形特性。这些新型宿主具有良好的光学、电学和热学特性,在有机溶剂中的溶解性也非常好。利用这些溶液加工的宿主,在一般荧光掺杂剂的作用下,最大电流效率达到了 7.8 cd/A。
