제목 Synthesis and Characterization of New Blue Materials Based on Hexaphenyl benzene with an electron donating moiety for OLED
초록 Five new Blue emitting compounds for OLED based on hexaphenyl benzene moiety. Physical properties by the change of the substitution groups of the synthesized materials were systematically examined. Photoluminescence(PL) spectrum of the synthesized materials showed maximum emitting wavelengths of about 400~447 nm in solution state and 451~461 nm in film state, indicating deep blue emission color. OLED devices were fabricated by the synthesized compounds using vacuum deposit process as a emitting layer. Device structure was ITO/2-TNATA 60nm/ NPB 15nm/ EML 35nm/ TPBi 20nm/ LiF 1nm/ Al 200nm. Especially, CIE value of 5P-VTPA can be applied to OLED TV application because of highly pure blue color. Also, 5P-VTPA and 5P-DVTPA exhibited superior thermal property such as high Td of 448 oC and 449 oC.
