Abstract

Tröger's Base (TB) scaffold has been exploited to create two novel amorphous hole-transporting materials (HTMs), i.e., TB1 and TB2, with high Tgs (152–156 °C) as alternatives to the popular NPB (Tg ∼ 95 °C). The hole-transporting properties of both TB1–2 are shown to be comparable to or better than that of NPB by contrasting the results of device fabrications with two different emissive materials that are TB-based and non-TB-based. This in conjunction with the ease of synthesis of TB1–2 should render them appealing choices as HTMs.
