New Conjugated Triazine Based Molecular Materials for Application in Optoelectronic Devices: Design, Synthesis, and Properties

Two novel triazine-based compounds with efficient hole-blocking ability were designed and synthesized, which promoted the performance of electroluminescent devices, especially for PLED even when Al was applied as the cathode. The results indicated that introducing electron-donating groups and extending π-conjugated were facile methodologies to improve the optoelectronic properties of the triazine derivatives.
