We developed highly efficient solution processable four yellow host materials (YH52, YH54, YH56, and YH65) for OLED Lighting. For developed four yellow hosts, we characterized physical properties of HOMO, LUMO, energy gap, m.p., and Tg, respectively. The Tg values of YH54, YH56, and YH65 were more than 145oC. The device performances of the organic light-emitting diodes(OLEDs) with four yellow host materials (YH52, YH54, YH56, and YH65) as a yellow host layer were investigated. Lifetime of yellow devices were estimated at an initial luminance of 1,000cd/m2. |
