Vacuum-vaporized organic low-molecular-weight materials are well known to polycrystallize easily. Suppression of organic layer polycrystallization is effective for the improvement of practical devices. For this reason, we observed the polycrystallization of two hole-transporting diamine derivatives for organic light-emitting diodes (OLEDs). In addition, we discovered that the organic alloy method is very effective for the suppression of polycrystallization despite its simplicity. We describe the polycrystallization of an organic vacuum-deposited layer.
