AbstractA copper-catalyzed Ullmann C-N coupling reaction was used for the preparation of a new carbazole-based HPU in good yield with a high molecular weight through a facile "AB(2) + A(2) + B(2)"-type approach. The HPU exhibited good solubility, high thermal stability with a T(g) of 196 degrees C, as well as a suitable HOMO level for good hole injection and transporting properties. A two-layer OLED device, using HPU as hole-transporting layer (HTL) and Alq(3) as the light-emitting layer, was fabricated to investigate the hole-transporting properties of HPU. The luminance efficiency reached 1.14 cd.A(-1) at the maximum current density of 1 240 mA.cm(-2), while the maximum luminance efficiency was 1.65 cd A(-1) indicating the high morphological and thermal stability of HPU.
