Synthesis and Electroluminescence Property of Deep blue Emitting Materials for OLEDs |
초록 |
Two new blue emitting compounds of TP-F-TP and TP-AF-TP for OLED based on fluorene moiety were demonstrated. Physical properties by the change of the substitution groups of the synthesized materials were systematically examined. Photoluminescence spectra of the synthesized materials showed maximum emitting wavelengths of about 380~400 nm in solution state and 440~450 nm in film state, indicating deep blue emission color. OLED devices were fabricated by the synthesized compounds using vacuum deposit process as an emitting layer. Device structure was ITO/2-TNATA 60nm/ NPB 15nm/ EML 35nm/ TPBi 20nm/ LiF 1nm/ Al 200nm. External quantum efficiencies and CIE values of TP-AF-TP was 6.05 % and (0.14, 0.10). TP-AF-TP exhibited superior highly blue quality and thermal property such as high Td of 448 oC. |
