The effective strategy of indirect linakge for constructing ternary ambipolar phosphine oxide (PO) hosts with the high first triplet energy levels (T(1)) was successfully demonstrated. interplay between chromophore, hole and electron transporting moieties effectively restrained. Both T(1) as 3.0 eV characteristics were perfectly realized, which consequently resulted in highly efficient blue-emitting phosphorescent organic light-emitting diodes low driving voltage stable efficiencies.
An ambipolar ternary deep-blue emitter with CIE coordinates of (0.15, 0.07) and high electroluminescent performance was constructed on the basis an insulated donor–π–acceptor system through indirect linkage.
