Conjugated asymmetric donor-substituted 1,3,5-triazines: New host materials for blue phosphorescent organic light-emitting diodes

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.

COMPOUND FOR ORGANIC ELECTROLUMINESCENT DEVICE AND ORGANIC ELECTROLUMINESCENT DEVICE

Disclosed is an organic electroluminescent device (organic EL device) which is improved in luminous efficiency, fully secured of driving stability, and of simple constitution. Also disclosed is a compound useful for the fabrication of said organic EL device. The organic electroluminescent device comprises organic layers including a light-emitting layer disposed between an anode and a cathode which are piled one upon another on a substrate and at least one of said organic layers comprises a compound for an organic EL device represented by general formula (1). Said organic layer is preferably a light-emitting layer containing a phosphorescent dopant. In general formula (1), X is a substituted or unsubstituted methine group or a nitrogen, Ar4 to Ar7 each is a substituted or unsubstituted aromatic hydrocarbon group or a substituted or unsubstituted aromatic heterocyclic group, and Ar4, Ar5 and the nitrogen to which Ar4 and Ar5 are joined or Ar6, Ar7 and the nitrogen to which Ar6 and Ar7 are joined may together form a nitrogen-containing heterocyclic ring.
