Electroluminescence Properties of Highly Efficient Dual Core Chromophores for Blue Emission |
| 초록 |
Highly efficient blue emitting materials consisting of dual core derivatives with triphenylamine side groups and symmetric structures were designed and synthesized. Of the synthesized compounds, DPA-AP-DPA was found to exhibit the highest EL device efficiency of 4.19 cd A-1 and 4.49 % EQE. 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. mTPA-AP-mTPA and TPA-AP-TPA exhibit EL maximum values of real blue color in the range 455 nm to 463 nm. The y values of their color coordinates are within the range 0.150 to 0.260, so these compounds exhibit good blue color coordinates for displays. |
