of dibenzofuran‐based ternary hosts were designed and prepared. The singlet energy levels and carrier injecting/transporting abilities were adjusted on the basis of the mixed meso and short‐axis linkages (see picture). By harmonizing the optical and electrical properties, the blue‐emitting diodes realized highly efficient blue electrophosphorescence with ultralow driving voltages.
设计并制备了一系列基于二苯并呋喃的三元主体。单重态能级和载流子注入/传输能力是根据混合的细观和短轴联系进行调整的(见图)。通过协调光学和电气特性,发射蓝光的二极管以超低的驱动电压实现了高效的蓝色电致磷光。
