초록
Novel blue host material, 4,4'-(dinaphthalen-2-yl)-1,1'-binaphthyl (DNBN), was designed and synthesized for OLEDs. In order to test the electroluminescent properties of DNBN, DNBN was used as the host materials for a blue emitter, PCVtPh. The device exhibited deep-blue emission with the CIEx,y coordinates (x=0.15, y=0.08) at 8.0 V, a luminous efficiency of 1.66 cd/A, a power efficiency of 0.77 lm/W and an external quantum efficiency of 2.30 % at 20 mA/
