  • Emitting layer composition: TATa or T-TATa isomer, NPB (N,N'-di(1-naphthyl)-N,N'-diphenyl-(1,1'-biphenyl)-4,4'-diamine), DPAVBi (2,5,8,11-tetra(p-tolyl)anthra[2,3-b:6,7-b']dithiophene) (blue dopant), and rubrene (yellow dopant).
  • NPB served as a blue host and hole transport facilitator.

    • Main Results:

    • The device employing the T-TATa isomer as a co-host achieved a luminance efficiency of 3.39 cd/A at 10 mA/cm2.
    • The device using the TATa material exhibited a lower luminance efficiency of 1.58 cd/A at 10 mA/cm2.
    • The T-TATa based WOLED demonstrated approximately twice the efficiency of the TATa based device.

    Conclusions:

    • The T-TATa isomer represents a promising new host material for solution-processed WOLEDs.
    • Substitution with a t-butyl group in the T-TATa isomer significantly improves device efficiency.
    • The T-TATa isomer offers a viable pathway for developing high-performance, solution-processed white OLEDs.
