Bis(4,6-diaryl-1,3,5-triazin-2-yl)arenes were prepared for new semiconductive materials, and their thermal and morphological natures were characterized. The glass formation properties of the materials were discussed with respect to the effect of the substituents and the molecular conformations. The carrier mobility measurement revealed that the bis-triazines showed ambipolar carrier transport capabilities in the films. We also demonstrated to fabricate an organic light emitting diode using the his-triazine as an electron transport layer.
