Compounds that are organic radicals that can have a dual function. The compounds can be fluorescent emitters that emit in the near-IR. The compounds can also facilitate reverse intersystem crossing (RISC) to convert triplet excitons in an OLED to singlet excited states to maximize utilization of generated excitons in the OLED and approach 100% internal quantum efficiency.
这是一个有着双重功能的有机基团化合物。这些化合物可以是发射近红外光的荧光发射体。这些化合物也可以促进反交替系统穿越(RISC),将OLED中的三重激子转化为单重激发态,以最大化利用OLED中产生的激子并接近100%的内部量子效率。
