Abstract

Bifunctional diamines (HTM + EM), namely, PTPA, PDPA and PCZL, have been designed based on a U-shaped phenanthrene scaffold and synthesized in a single step with good isolated yields. In particular, PTPA is shown to exhibit deep blue emission (CIE_x,y ∼ 0.16, 0.06) with respectable efficiencies in a simple double layer device.
