영문 초록

New electroluminescent materials base on anthracene chromophore, [9.10-bis(${\alpha}$ 수식 이미지-naph -thylethenyl) anthracene (${\alpha}$ 수식 이미지-BNA)] were newly synthesized. The anthracene derivatives with bulky substituent possessed high melting point and they gave stable amorphous films through vacuum - sublimation methods. Three types of electroluminescent devices were fabricated with double layer and triple layer structure : ITO/TPD/emission layer/MgAg, ITO/emission layer/ OXD-7 and ITO/ TPD/ emission layer/OXD-7/MgAg, respectively. In three types of devices with the emissive layer of ${\alpha}$ 수식 이미지-BNA, efficient orange electroluminescence was observed. In the triple layer device whit a emitting layer of 20 nm thickness , maximum luminance was about 10000 cd/ $m^2$ 수식 이미지 at an applied voltage of 10v and maximum external quantum efficiency was 1.0%.
