Three-layer electroluminescent devices fabricated from 1,3,5-tris(2-(9-ethylcarbazyl-3)ethylene) benzene (TECEB) (see Figure) are shown to exhibit bright and efficient white light with a maximum luminescence and current efficiency of 1200 cd m–2 and 1.1 cd A–1, respectively. It is suggested that these represent the best reported results for single-emitting-component white electroluminescent devices to date.
