Abstract

Easily accessible bis-1,2,4-triazines can be converted to corresponding pyridines by the Boger reaction, opening up convenient synthesis pathways to salen-type tetradentate dianionic ligands. The new ligands were used to prepare highly luminescent ONNO Pt(II) complexes in which the position of the cyclopentene rings significantly influences the solubility and photophysical properties. The complexes were evaluated as phosphorescent emitters in solution-processed organic light-emitting devices (OLEDs), showing efficient single-dopant candlelight electroluminescence.
