Based on a p-type scaffold, a novel solution-processable phosphonate functionalized deep-blue fluorescent emitter has been designed and synthesized. The corresponding non-doped single-layer SMOLED shows a peak current efficiency of 0.76 cd A−1 with CIE coordinates of (0.15, 0.09), which is about three orders of magnitude higher than that of the prototype with tert-butyl substituents.
基于 p 型支架,我们设计并合成了一种新型可溶液加工的
膦酸盐官能化深蓝色荧光发光体。相应的非掺杂单层 SMOLED 的峰值电流效率为 0.76 cd A-1,CIE 坐标为 (0.15, 0.09),比带有叔丁基取代基的原型高出约三个数量级。
