Abstract

The capabilities of readily prepared and sublimable Pt(II) Schiff base triplet emitters as OLED dopants have been examined; maximum luminous and power efficiencies and luminance of 31 cd A⁻¹, 14 lm W⁻¹, and 23,000 cd m⁻², respectively, and white EL (CIE: 0.33, 0.35) by simultaneous host/dopant emission, have been achieved.
