27. Partial aggregation occurred to form dark spots when the device B was fabricated, and the data were collected using a uniformly illuminating area. We also fabricated an OLED device including compound 3c (doped with PPB) as the HIL. However, significant aggregation occurred, and its OLED characteristics were exceptionally poor, probably because of the aggregation.
