Fully substituted ethylene as a new class of efficient sky-blue emitting materials for OLEDs

We synthesized new blue and bluish green emitting materials by using fully substituted ethylene moieties. Multi-layered EL devices were fabricated with synthesized materials and evaluated in terms of emission color and luminescence efficiency. TBBPE[EML 2] device showed bluish-green CIE value of (0....

Summary:We synthesized new blue and bluish green emitting materials by using fully substituted ethylene moieties. Multi-layered EL devices were fabricated with synthesized materials and evaluated in terms of emission color and luminescence efficiency. TBBPE[EML 2] device showed bluish-green CIE value of (0.236, 0.412) and 5.02cd/A at 10mA/cm 2 . BPBBPE[EML 3] device also showed sky-blue CIE value of (0.218, 0.355) and 2.31cd/A at 10mA/cm 2 .
