摘要：

The development of highly efficient phosphorescent molecules has approximately quadrupled the quantum efficiency of organic light emitting devices (OLEDs). By harnessing triplet as well as singlet excitons, efficient molecular phosphorescence has also enabled novel studies of exciton physics in organic semiconductors. In this review, we will summarize recent progress in understanding exciton formation and energy transfer using phosphorescent molecular probes. Particular emphasis is given to two topics of current interest: energy transfer in blue phosphorescent OLEDs, and quantifying the formation ratio of singlet to triplet excitons in small-molecular weight materials and polymers.
