1. IntroductionIn the realm of organic light-emitting diodes (OLEDs), triarylamine derivatives, which are commonly employed as hole-transporting or luminescent materials, hold an exceptionally crucial position [1,2,3,4]. They exhibit a relatively high hole mobility and, when utilized as materials for the hole-transporting layer, can enhance the recombination efficiency of excitons within the emitting layer and improve energy utilization, thereby augmenting the device’s luminous efficiency [5].
