Conjugated asymmetric donor-substituted 1,3,5-triazines (ADTs) have been synthesized by nucleophilic substitution of organolithium catalyzed by [Pd(PPh3)4]. Theoretical and experimental investigations show that ADTs possess high solubility and thermostability, high fluorescent quantum yield (35 %), low HOMO (-6.0 eV) and LUMO (-2.8 eV), and high triplet energy (ET, 3.0 eV) according to the different substitution pattern of triazine. The application as host materials for blue PHOLEDs yielded a maximum current efficiency of 20.9 cd A-1, a maximum external quantum efficiency of 9.8 %, and a brightness of 9671 cd m-2 at 5.4 V, making ADTs good candidates for optoelectronic devices.
