In this paper, the exciton behavior was analyzed using DMAC-DPS with D-A-D structure as a sensitizer, it showed aggregation-induced emission (AIE) characteristics. We predicted the device performances by calculating the kCQ of DMAC-DPS. In addition, TTA and STA were analyzed according to the doping concentration to understand the exciton behavior.
